Sau Khi Tiêm Vaccine Bao Nhiêu Lâu Thì Cơ Thể Được Bảo Vệ

How long does it take to get vaccinated? We all know that there are many vaccines that have been reported to us, right? What is its protection ability? For example, we will have Pfizer vaccine that protects up to 95% Moderna vaccine protects 94% or AstraZeneca protects 70% Sinopharm protects 78% However, this is the protection ability of the vaccine when we get two shots That is, people will count after 14 days in the second shot This is our protection ability However, at the moment, how is the situation of vaccines? Many people are still vaccinated with only one shot There are people who have been vaccinated with the first shot and it's time to get the second shot However, we have not been vaccinated So here we have a lot of people wondering If we get one shot, will it be able to protect us? Before we answer these questions, we have to understand the immune system of our body How does it work? Let's imagine that our immune system is like our army and the virus is like the enemy to invade our body attack our body At the beginning, we will not know what our enemy is like We will not know what our enemy is using to attack us Until the virus invades us the immune system has just begun to produce antibodies to be able to destroy the virus It's like this When the enemy starts attacking us For example, if the enemy attacks by sea then our immune system will be trained that we need to prepare for defense But if the enemy starts attacking by plane then our army will be trained to defend with missiles However, at the beginning, we will not know what we need to defend Therefore, we will need about 2 weeks For example, when the virus invades our body At this time, our body will have immune systems It will begin to recognize those antibodies to put them into our immune system We will need 2 weeks to produce antibodies to destroy the virus Not when the virus invades Because when the virus invades the body does not have antibodies to destroy And what is the vaccine for? To let us know what our body recognizes That is, the enemy will be like that for us to be prepared And when the virus invades our body At this time, our cells will recognize those antibodies and put them into our immune system It includes our blood vessels to be able to produce the immune system And in these blood vessels we will have a place where there are bacteria such as in the neck area or the armpit area And every time we are infected or we are infected with the virus we start to see these areas of bacteria it will swell up and it hurts in that area That's when our immune system is producing antibodies to prepare to destroy the virus And what is the time frame we remember here? That is, we will need 2 weeks for the immune system to produce antibodies or train an army team to be able to defend so that next time if the enemy attacks the virus attacks at this time our body has the ability to protect our body So here we will know that it will take 2 weeks to start producing antibodies So after everyone has been vaccinated we will need 2 weeks for our body to produce antibodies Many people after we have been vaccinated and we are immediately infected So many people say Ah, this person has been vaccinated This vaccine is not good because it is still infected Because within 2 weeks our body is not immune So no matter which vaccine you get during that time it has not yet formed antibodies in our body we still have the ability to be infected as usual You should remember that And what is the time frame? That is, after 2 weeks for our body to produce antibodies However, when our body has produced antibodies it is like our army team has been trained has been recruited However, after a while it will start to weaken gradually and at this time we will need a second nose to return to continue training our army system And that's why we have a second vaccine nose So here we will look at some studies about the effectiveness of vaccines Here, for people to compare vaccines in time or in the first and second nose not all vaccines have reports like this some have reports And on our screen we will see its effect when we compare between 2 vaccines Pfizer and AstraZeneca And we see that when we compare for example, for the green vaccine it has a high significance that is, this study has a high significance while for the yellow or orange vaccine the significance level will be lower because its number is less And we will see that for example, for the Pfizer vaccine when we take the first nose our ability to protect against infection is from 55% to 70% that is, it has the ability to protect after 2 weeks when we get this Pfizer vaccine Or for the AstraZeneca vaccine for the first nose after 2 weeks when we get it its protection ability is from 55% to 70% However, when we see if we increase in the second nose like Pfizer vaccine or Moderna vaccine or Sinopharm we will see that the time to take the second nose is about 3 weeks and we may extend it to 6 weeks Here, you can extend it to 3 weeks to ensure that its effect will be better than taking it early Many people say or we take 2 noses is it possible? What will people remember? We will need 2 weeks for the immune system to be created and then we will need a time to take the second nose to continue making the immune system it will increase the effect so we take it early the immune system has not yet been created and it will make us ineffective and for Pfizer vaccine or Moderna we will need 3 weeks 3 to 4 weeks that is the time we need to take the second nose However, we may extend the time to 6 weeks to take it still ensures the effect As for the AstraZeneca vaccine the time that the manufacturer advises is from 4 weeks to 12 weeks and we may extend it after 12 weeks it still gives us our result and we see after the first nose it has the ability to protect from 55% to 70% both are the same so if you extend it for Astra or Pfizer the first nose the ability to protect will be the same but when we extend it to the second nose here for Pfizer it protects from 85% to 90% and for Astra it protects from 60% to 90% 65% to 90% this is one of the research when people compare this vaccine some reports we will see when we see some reports on Google and we see for Pfizer it protects 95% it has a lot of research and then people will combine the research together and give out a final fixed number and here maybe people are researching some research in UK or US people are researching on a research like this and we will see after two noses Pfizer protects better than Astra if we extend two noses but extend one nose the two are still the same for a research like this but there are a lot of people will ask that if we extend the first nose too long and we can't extend the second nose then what? we will have another research together we will see that if we extend after we extend two noses at the present time its effect can still maintain its effect can still maintain its effect for a long time up to the present time its ability is still protection people see its protection decreased but not much however if we extend one nose we will see in this research we will see that if we extend one nose in this research they are researching on AstraZeneca vaccine and after they extend the first nose from 22 to 30 days that is after 3 weeks 3 weeks 21 days and from 22 to 30 days its protection is 76.7% from 30 to 60 days its protection is 72.8% and from 30 to 90 days its protection is 78% and in total from 22 to 90 days that is after 3 weeks 3 weeks 3 months it will protect 76% however if we postpone the vaccination and we do not have the vaccine to be vaccinated and after 90 days we see its effect decreased to 31.6% we see its effect decreased 120 days its protection decreased therefore we need a second nose to increase its effect after we vaccinated the second nose its effect is maintained nearly maintained but if we only have one nose after a while its effect will decrease decrease for Astra after 3 months that is from 90 days to 120 days we see its effect from 78% to 31% therefore we need a second nose so many people after the first nose and we think we are protected but in fact its protection is not 100% for us and we must follow the 5K that is limit contact and hand washing and all those things here when we see this what is it for? so we will know that we need something to protect because at this point everyone wants to get 2 noses but if we don't have enough vaccine at this time and if we get 1 nose what will we know? after 2 weeks we have antibodies and best after 3 weeks that is 21 days it will be protected and after 3 months that is 90 days its effect will decrease and we need a second nose and that is some of the scientific sharing about the effect of vaccine after we get it here I will note some main points like this that is the effect reported in research is usually reported after 2 noses but if we only have 1 nose usually after 2 to 3 weeks and here it is best after 3 weeks its effect will be almost like our reports but it will decrease gradually and for AXA after 3 months its effect will decrease and we need a second and that is some of the main information about vaccine for our body I hope after watching this video we will have more information about vaccine and we will need information to protect ourself during this time when vaccine is still rare ok see you in the next videos don't forget to subscribe Dr.Ngoc's so we can receive new information everyday bye
