Doctors reiterate COVID-19 vaccine Thailand chooses safety, asks the NACC to join in the injection to help the nation
On January 26 at the Ministry of Public Health (Ministry of Public Health) Prof. Dr. Prasit Wattanapa Dean of Faculty of Medicine Siriraj Hospital Mahidol University Announcing the procurement of a vaccine against the coronavirus 2019 or COVID-19 that COVID-19 If in the air at 25 degrees Celsius without sputum. Or saliva envelops cells Will dissolve within minutes But if there is an encapsulation, it can last up to an hour but cannot divide. This is because viruses can only multiply when they enter the organism and spread out.
Prof. Prasit said that simulating herd immunity against COVID-19 (Herd Immunity) if a certain number of people were gathered in the community. Not everyone has immunity. Some people wear a mask. And those who do not wear masks can get the infection Some people died during the infection. But the nature of COVID-19 People who received the infection did not die in the second week, it will build up the immune system. While the virus is still in the community, it will infect new groups and in the same group will occur in the same way as the first group, with some deaths. And those who have not died will become immune.
“In the end, there will be a lot of immune people in the community. There are some people who still protect themselves. Not infected and immune But the main thing is Some people in the community disappeared because of their death. It means the exchange of immunity, ”Prof. Prasit said, and if simulating a new situation, most people in the community are immune. There are some that protect themselves from infection, and a few do not have immunity. Then don’t protect yourself Became infected and died But the rest of the people are immune to the immune system, so airborne viruses cannot enter the body. Because each person has a landscape The virus will eventually decay.
Prof. Dr. Prasit said that it was the reason it was said that If the proportion of people in a particular country is large enough Will make the virus unable to stay in that area And will eventually dissolve For COVID-19 The numbers are not clear. Because it is a new disease in the past, such as measles, the proportion of people who have an immunity in the country is 95%. Measles will disappear from the country. A small chance Even though the vaccination is still required
Prof. Dr. Prasit said, however, there are 2 ways to create an immunity. 1. Caused by infection. The trade-offs are mortality and 2. Vaccination by COVID-19. It is estimated that 70% of the country’s population. Should make the virus disappear Because when people have high A lot of viruses cannot enter. It will soon disappear And if really disappeared forever Therefore able to stop wearing a mask Which some people understand that Vaccinated and have immunity Then take off the mask
“This one is really dangerous. And in foreign countries that have already been injected Reiterate this very much This information is required to simulate the situation. If Thai people help to get vaccinated, we will help the country because as soon as Thais are immune enough, COVID-19 cannot survive in the country. Some people are afraid of dying from the virus. But some people fear dying from vaccines. Therefore, the method of selecting a vaccine must be emphasized. 1.Safety is the first Nobody wants to die from the virus. And no one wants to die because of the vaccine and 2. Efficiency, ”Prof. Prasit said.
Prof. Prasit said the latest global data on January 14th, there were 20 vaccine companies that had passed through phase 3, studying at least 30,000 people to look at safety and efficacy. And at present there are 4 technologies of vaccine production: 1. mRNA technology from the United States. That Thailand has not imported No one has ever used this technology to make vaccines.
“This is the first time While the vaccine is effective against the virus at up to 95%, it is not necessary because 50-60% is sufficient. For example, the annual flu vaccine is only about 50-60% effective. It is important to get the vaccine and get it. Not severe and not fatal This is a big goal. It is not non-infectious. Fatalities have also been reported following vaccination. And theoretically there is still a chance of causing long-term complications. But there is no evidence at this time, ”Prof. Prasit said.
Prof. Dr. Prasit said that while the vaccines from the company AstraZeneca The principle of this vaccine is to remove a virus that does not cause disease in humans. And took the genetics of COVID-19 That make proteins (Protein Sprite) until a large number of outbreaks occurred. Go into contact with this virus and enter the body. Which our immune system will find that this virus is foreign And remember that this is a disease When we remember, our immune system eliminates these viruses, so this type is highly effective at 90%, all requiring two injections, but the vaccine doesn’t use COVID-19, making it affordable. Currently, in Thailand, about 5 US dollars per dose, in theory, the virus is not inserted. Chances of complications Allergies are likely to be less. The results of the study during the test phase 1, 2 and 3 were found in 2-3 cases, but the final result was not about vaccine It is considered safe. However, this technology has other companies such as Russia, but Thailand has not brought it in.
Prof. Dr. Prasit said there was another Thai imported in February, the Sinovac, because AstraZeneca alone might not be enough. The COVID-19 Sinovac vaccine is the use of technology that carries the coronavirus. And weaken Until unable to do harm And imported into our body until our landscape recognizes this virus And when the infection enters, it will be dealt with It is an old technology but has a high price because it has to be treated to weaken the infection so that it does not spread. Which results in about 50 percent that are sufficient for the immune system It is the same technology as the flu vaccine. Which is very safe Because I have known for a long time
“These two vaccines, both from Astra, and Sinovac, will be imported into Thailand. And when it comes in and every injection, it covers approximately 50-60 percent of Thais plus a handful of people who are already infected. And have immunity Which should be about 60-70 percent. In total, it is likely to reach a number that may cause COVID-19. This was the reason for the immunization to save the nation. Therefore want you to understand these matters And this is considered as fortunate We are not so tech-savvy that we only have new ones, but these two that are considered safe, ”said Prof Prasit, and that this vaccine hasn’t been immune to COVID-19 for very long, it might not survive. More than 1 year may need to be injected once a year. But still unable to conclude at this time
Prof. Dr. Prasit Discusses cases of vaccination helping the nation But why must it be voluntary? Each vaccine is said to be 100% safe, however, I don’t want to enforce it. But I want to invite them to get vaccinated because these two vaccines are safe If there are side effects, it’s not much
