Dr. Prasit pointed out why the injection. “COVID-19” to prevent the virus entering the body Because I don’t know who is immune But must consider safety Emphasize to take care of your health in accordance with the principles of bioavailability strictly. I do not trust even after vaccination.
On January 19, 64 Prof. Dr. Prasit Wattanapa, Dean of the Faculty of Medicine Siriraj Hospital Mahidol University discloses the situationCOVID-19 In Thailand, it is said that monitoring of the situation in Malaysia is still required. With the rate of new cases of more than 3 thousand people a day because of the high infection rate. More worrying than Myanmar Because the number of new cases is high Which could lead to the closure of the country And causing problems to move workers using Thailand as a means of passage While Myanmar has a tendency to reduce infection, it is still hundreds and ready for injection.VaccineFeb 64
While Thailand has a rate of around 200-300 new cases a day, Tuo Mai is alarmed by the number of patients alone. Must see in detail Because the reason for the more patient numbers comes from proactive screening Which is considered a good result to be able to find the patient But one must be aware of the infection in the country that did not come from proactive screening, the increase in Thailand has three components.
1. Proactive examination in foreign workers The more you check, the better. This will know the total number of infections so that they can prevent them from spreading the infection.
2. Infection rates in countries not involved in proactive testing Especially knowing the source It is very important to be vigilant.
3 groups traveling from abroad When you look at the increasing numbers, you will know how scary or not scary.
For an important mutation of the infection. COVID-19 This is normal Currently, the strain found in China, Wuhan D614, is rare, and the newly discovered G614 strain is the most common of all epidemics worldwide.
The B1.1.7 strains are now 50-70% faster than the original strain, but there is no evidence that people infected with this strain will die. B 1.1.7 is found in a wide variety of countries in Europe, the Middle East, Asia, Africa, Australia, Canada. Almost all of them will cover the species that are spreading at this time. But mutation Of COVID-19 Continuous May affect vaccine production against strains It needs to be improved to maintain efficacy in the future and may result in yearly vaccinations. Such as those found in the flu Which the manufacturer may need to improve To be effective or have to be vaccinated every year
It is now too early to assess the results of the vaccine after just one month of global use. And the deaths of the entire world are likely to continue. And the number is higher than the outbreak in the first round For example, the United States, who started vaccination on Dec. 14, 2020, now has an average of 300,000 new cases per day and constant death rates.
The United Kingdom where the mutation was found And vaccination began on Dec. 8, 20. New cases and mortality rates are also promising, France has people against vaccination. The goal to complete the injection of 1 million people in January, 64 out to the end of February 64, Japan prepared to vaccinate early. Feb. While there are new cases And the mortality rate was so high that the country had to shut down because it was an aging society, South Korea had a new number of cases. And the death rate has increased By preparing to get vaccinated in February ’64
Dr. Prasit said that about 95% of the patients were infected.COVID-19 Will have immunity Depending on the severity of the disease Very severe, very immune levels And immunity will stay at least 5 months, but not persist for long Causing a chance of recurrent infection And there is still no evidence of group immunity as it is an emerging disease. It is just speculated that if there is an infection 60-70% may develop a group immunity. And no one can predict that people who are already infected will be safe. Because in this second round there were deaths who were only 30-40 years old
Immunization will make people without immunity. To build immunity Safety must be given to the vaccination. Because we avoid death from virus infection. But must not cause death from vaccination
Dr. Prasit said the vaccination to prevent the virus entering the body. Because the virus will increase in number, must enter the person If you cannot enter, it will disintegrate. That is why vaccinations are required. Because I don’t know who is immune But must consider safety Regardless of the vaccine, follow-up is required. Because each vaccine has a different manufacturing method and is suitable for each person differently. Like the influenza vaccine, it is effective at 50%. People who get it are more likely to be infected with mild illness. Low mortality
Considering the use of the vaccine, other components must be considered, such as its storage at very low temperatures. If it does not meet the manufacturer’s instructions, it will degrade performance. The injection was not useful. Choosing a vaccine does not have to be a highly effective approach, close to 100%, but at least 50%. “
Development of vaccinesCOVID-19 At present, 20 are used as an emergency, 8 companies are generic vaccines, 2 companies have discontinued 1 company, with monitoring reports of side effects and post-vaccination complications of companies. Come out continuously For example, the UK will change its vaccination pattern from a second shot three weeks after the first injection to more nationwide carpeting and then expanding it. The second injection time is in 12 weeks.
The most used vaccines at the moment are Pifer BioNtech Most used in the world, need to inject 2 needles, vaccine efficiency 95%, but need to store temperature minus -70 degrees
Modern Injecting 1 dose is 94% effective, but I can’t tell how long my immune system will last. Canadian use for side effects: headache, fatigue, joint pain, chills.
Gamaleya Russia’s efficiency 96% or more, the purchase of the Sputnik V vaccine, has an agreement to produce it for Argentina, Razil, India, Venezuela.
Astra Seneca of the United States, the trial group lost one case, the United Kingdom. And Argentina The emergency use is guaranteed that the injection of 1 dose is 64.1% effective, the full two doses are 70.4% effective, but if the injection half dose followed by 1 dose will be as effective as 90%. Osise already has the Astra vaccine in line.
Another vaccine that Thailand will adopt is shinovac, a technology that uses old technology that brings germs to weaken or die before, familiar to the world. Which will be ordered to be used in February Which Sinovac vaccine 50.38% efficiency, advantages, fast production and still have another reliable company. That can be imported into the Chinese sinopharm sinopharm.
Dr. Prasit said that people would be confident about the safety of vaccination.COVID-19 And must understand that vaccination In order to reduce the spread Reduce the severity of illness And reduce deaths At the same time, everyone must continue to take care of their own health in accordance with the principles of life. Without trust even after being vaccinated
Even after the vaccine has been released But all Thai people still play a role in stopping COVID-19. Do not pay off too quickly. The vaccine imported is relatively safe. Be confident about the vaccines that will be injected. Still need to wear a mask, wash your hands, keep a distance Out of the community
