[00:00:01] Vaccination may not create a charitable force, but it will definitely make the body produce
[00:00:04] antibodies. Therefore, the doctor who is currently breastfeeding also suggests
[00:00:08] getting vaccinated as soon as possible, so that the child can also have protection
[00:00:12] . This is because after the mother is vaccinated, there will be antibody
[00:00:16] components in the milk. Therefore, the infant can get antibody
[00:00:19] protection through breast milk and resist the new coronavirus
[00:00:22] .
[00:00:30] But with the new coronavirus pneumonia , many breastfeeding
[00:00:33] mothers are also very worried about what impact
[00:00:37] getting vaccinated will have on their children ? In fact, we encourage
[00:00:41] breastfeeding mothers to get vaccinated, because their babies
[00:00:44] basically cannot be vaccinated yet
[00:00:47] .
[00:00:57] So, in other words, if a breastfeeding
[00:01:01] mother gets vaccinated, she not only gets
[00:01:04] protection herself, but also the child
[00:01:08] who drinks her breast milk also gets the protection of these antibodies, so it's a bit
[00:01:12] like one person gets vaccinated and two people benefit . Before birth, babies
[00:01:15] get immunity from the mother's placenta. After birth, they get it through breast
[00:01:19] milk, and the immune system of newborns is not yet mature. Therefore,
[00:01:23] to resist virus invasion, the antibodies in breast milk become the
[00:01:27] key. In our immune system ,
[00:02:06] although the concentration of antibodies in breast milk will decrease over time, continuous supplementation is the
[00:02:10] key. These antibodies will actually
[00:02:14] circulate to the mother's breasts, and some receptors
[00:02:17] in the breasts will secrete them into her milk after receiving them,
[00:02:21] so the child can actually consume the antibodies produced by the mother after vaccination,
[00:02:25] because the child continues to breastfeed, so it can
[00:02:29] continuously consume these antibodies, which provide continuous
[00:02:32] protection, because babies' ability to produce
[00:02:36] antibodies themselves is still relatively weak. However, doctors explain
[00:02:40] that antibodies in breast milk do not enter the baby's blood, but rather cover the oral cavity,
[00:02:44] throat, intestines, and other places before being digested,
[00:02:48] creating protection. In breast milk, the more important
[00:02:51] and most important antibody component is IgA.
[00:02:55] So, when they consume this antibody, they actually ingest it. This
[00:02:58] antibody virus is
[00:03:19] . Therefore, as long as the mother continues to breastfeed, the baby can get antibody protection
[00:03:23] .
[00:03:28] Doctors also remind that if mothers feel unwell before vaccination, it is best to wait until they recover.
[00:04:01] After the epidemic, there are many sports enthusiasts outdoors, but whether it is
[00:04:04] jogging or cycling, you still have to wear a mask. Although
[00:04:08] exercise can boost immunity, doctors remind that exercising with a mask
[00:04:12] still carries many risks.
[00:04:24] According to a study in the British Journal of Sports Medicine , if you wear a mask while running intensely
[00:04:28] on a treadmill, the maximum
[00:04:35] , especially during high-intensity, high-oxygen consumption exercise, if you don't
[00:04:39] get enough oxygen, it may cause hyperventilation, a decrease in oxygen concentration,
[00:04:43] leading to dizziness, and the risk of sudden death
[00:04:45] .
[00:04:48] I used to be, that
[00:04:51] one.
[00:04:54] It's quite busy, right ?
[00:04:59] We. When climbing stairs, we wear masks.
[00:10:03] All the B78s are attracted
[00:10:05] when fighting against him, it will be difficult to have some of us
[00:12:25] If the high fever persists, special attention should be paid to whether it is a warning
[00:12:29] sign of other diseases. Seek medical attention immediately. Every symptom is
[00:12:32] a signal sent by the body
[00:12:34] .
[00:12:37] When taking temperature, many shops now use a hand temperature
[00:12:41] gun, which can measure hand temperature and spray alcohol for disinfection
[00:12:45] at the same time. However, experts remind that hand temperature is easily affected
[00:12:48] by peripheral circulation and external factors, so it is not
[00:12:52] suitable as a basis for judging fever . So
[00:14:25] experts say that to measure correct body temperature, it is usually done through several
[00:14:29] parts. Among them, rectal temperature and ear temperature are the closest to the true internal
[00:14:33] body temperature. However, due to convenience, ear temperature is currently the most commonly
[00:14:37] used data, and oral cavity temperature is usually 0.5 degrees lower
[00:14:40] than the central body temperature . The reason is that it is easily affected by diet.
[00:14:44] Under the armpit, it is often evaporated by sweat, and the average is 0.8
[00:14:48] degrees lower than the true body temperature. The commonly used forehead
[00:14:52] temperature, due to sweat, rough skin, or makeup.
[00:14:55] influences, so the measured body temperature is usually low.
[00:15:00] The entire body, as well as some nerve reactions, are actually more sensitive here. So all body reactions in the head are actually quite accurate. Also, because the temperature measured in different parts will have a difference, the standard for judging fever is also different. Generally speaking, a temperature above 37 degrees is considered fever. Oral temperature is 37.5 degrees. If the ear temperature on both sides is higher than 38 degrees,
[00:17:33] Welcome back to "Discover Science." Wearing masks has become a nationwide
[00:19:07] The fusiform gyrus is located at the bottom of the cerebral cortex and is part of the temporal
[00:19:11] and occipital lobes. In this area, there are some nerve cells specifically
[00:19:15] responsible for processing facial features. It is a massive internal database of human
[00:19:19] faces and a facial recognition system. This means that
[00:19:23] if you see a man with single eyelids, your brain's database starts searching for
[00:19:26] single-eyelidded men you've seen before and averages them to create
[00:19:30] a face. At this point, the hidden true face will gradually
[00:19:34] emerge in your mind. This automatic completion of unseen parts
[00:19:38] into a whole is scientifically known as Gestalt
[00:19:42] psychology
[00:19:43] .
[00:19:48] It should come in handy. It's like what I just said, under this obscured clue, it's a filling in
[00:19:52] under obscured circumstances. So how do we fill it in?
[00:20:06] This nose itself has it.
[00:20:50] Research has shown that babies are particularly fond of looking at
[00:20:53] human faces from birth, so they can quickly distinguish the features of their parents
[00:20:57] and learn to distinguish happy, sad, and surprised
[00:21:01] facial expressions. As they grow up, these
[00:21:05] faces they have seen will become their brain's recognition
[00:21:08] database
[00:21:10] .
[00:22:09] If worn, it must be worn correctly to effectively provide protection.
[00:22:15] I'm Kevin, thank you for watching.
[00:23:50] A story of chasing dreams. Exploring new scientific experiences. Hello everyone, welcome to Discover Science. I'm Wu Wen. With the acceleration of new vaccines, many people in Taiwan are already preparing for their second dose. However, previous experience shows that the side effects of the second dose will be more obvious than the first dose. What is the reason for this? Let's continue to explore.
[00:24:48] My left hand is extremely painful,
[00:24:52] bursting with soreness. When I woke up this morning, I originally wanted to tie my hair and put on clothes,
[00:24:56] but suddenly I found it was really too painful. I couldn't lift my arm
[00:25:00] and it was very difficult to move this arm. Ms. Chen in the United States
[00:25:03] received her second dose of Moderna vaccine 28 days later,
[00:25:07] but the next day after the shot, she experienced severe side effects. Afterward,
[00:25:11] her entire back, including now, is still
[00:25:15] sore. Every inch of her skin that touched the bed,
[00:25:18] I felt
[00:25:22] pain. I even took two painkillers tonight. Basically,
[00:25:25] it's like the feeling of a severe cold
[00:25:28] .
[00:25:31] And my head feels heavy
[00:25:33] .
[00:25:40] Why is this? Scientists speculate that it may be related to
[00:25:44] the pre-existing immunity triggered by previous antigens or other vaccine
[00:25:48] components.
[00:25:50] Previously, these things in your body have already recognized or attacked these things, causing a larger reaction.
[00:25:56] The body's immune system, when it first encounters the vaccine, activates two important types of white blood cells. One of them is B cells.
[00:26:02] Its main function is to produce antibodies against viruses. The other is
[00:26:06] memory T cells, which can identify the characteristics of the enemy and improve the quality of antibodies.
[00:26:10] However, both types of cells are produced in large quantities only after the second dose is
[00:26:14] injected. Therefore, the body's immune response may be stronger
[00:26:18] than the first time, and the side effects may be more obvious. The second time,
[00:26:22] when it encounters the same vaccine and antigen, this elite force will start to
[00:26:25] rapidly expand.
[00:26:29] And these will become more reactive.
[00:26:48] The side effects of the second dose are not very obvious. Experts say that this is closely related to the different characteristics of vaccine principles.
[00:26:55] In addition, many studies have found that the second dose of mixed vaccine seems to produce stronger side effects than unmixed vaccine.
[00:27:02] .
[00:27:53] Especially, side effects will still vary to some extent depending on individual physique.
[00:27:57] Regardless of whether the first or second dose causes a greater reaction, people should still actively get
[00:28:01] vaccinated to be effective.
[00:29:02] It will cause blood flow, this is called a blood clot
[00:29:06] .
[00:29:11] A general blood clot is a blood clot composed of platelets and fibrin
[00:29:15] that blocks blood flow, causing thrombosis. However, the blood clot
[00:29:19] caused by the vaccine is a special autoimmune antibody that a very small
[00:29:23] number of people produce after the vaccine is injected into the body.
[00:29:27] This special antibody will attack platelet factor 4 (PF4).
[00:29:31] Other common affected areas also include. Therefore, if there is abnormal pain or swelling, special attention should be paid to it, and the veins will also ache. Venous thrombosis is very common, and these are all common causes of pain.
[00:30:57] Stomach ache, belly ache and those.
