“Mor Yong” Summary of 10 points about “COVID-19 vaccine” The latter had been spoken of very badly. Ready to point to time as proof. that the information stated is correct in all respects
On December 25, 2023, Prof. Dr. Yong Phuworawan, Head of the Center of Specialization in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Post a message about “COVID-19 vaccine, time will tell” By stating that
In the first phase, the vaccine was started to be used in Thailand. with very limited vaccines in high demand Thailand initially received inactivated vaccines. My team and I have carried out a detailed research study. with high cross injection and is correct information But there was much slander. was drawn into politics Now the passage of time has proven that The information stated is correct in every respect. This year is the 4th year of the outbreak. Let’s be a society rich in wisdom. I would like to summarize information about the COVID vaccine. for society to understand
1. There are 4 types of COVID-19 vaccines: A. inactivated vaccine (sinovac, sinopharm) B. virus vector (AstraZeneca; AZ) C. mRNA vaccines include (Pfizer, Moderna) D. Protein subunits include Novavax.
2. All vaccines are equally effective. It will be effective in the first months after injection and for longer periods of time. Will not be able to prevent infection. But it is part of reducing the severity of the disease. The efficiency is therefore no different. There is no divine vaccine.
3. Inactivated vaccine Stimulates immunity as much as natural infection. But lower than viral vector and mRNA vaccines.
4. The most commonly used vaccine in the world is the inactivated vaccine, used for more than half of the vaccine doses injected in the world. Especially used in Asia and Africa, including South America. Countries using the vaccine have not had as high a death rate as those using the mRNA vaccine. The United States has had more than 1 million deaths, far behind China. Or even Indonesia and Thailand, the death rate is much lower than America and Europe.
5. All vaccines have complications that can occur. According to the principles of the vaccine If it is an inactivated vaccine, the same technology will be used. The same is true for vaccines. Hepatitis A, Infectious Polio Side effects such as fever and aches are much less common than with viral vector and mRNA vaccines, including symptoms of atherosclerosis and myocarditis. And diseases related to the immune system are less common.
6. Inactivated vaccines are much cheaper than mRNA and are easy to store and use. The virus kills 1 person per bottle, while 7-10 people per bottle of mRNA cause a lot of waste. And must be stored at a temperature of minus 70 degrees Celsius, but inactivated vaccines are stored at a normal refrigerator at 4 degrees Celsius. Management is easier. Less wastage
7. Cross-regimen vaccination It is a solution that produces the final result. of inactivated vaccines that have a high level of immunity, such as giving 2 doses of inactivated vaccine and stimulating with mRNA. The results It is equivalent to giving 3 doses of mRNA and is accepted worldwide. The World Health Organization also accepts the cross formula.
8. Providing cross formulas used in Thailand The first dose is administered with Sinovac and then followed by AZ vector virus. Immunity is better than giving 2 doses of killed virus or 2 doses of virus vector and is accepted by the World Health Organization.
9. Inactivated vaccines have much less side effects such as fever and others than with vector and mRNA viruses. AZ vector virus vaccines will have many side effects in the first dose. And it will be less in the second and third doses. At the same time, immunity is less likely because the vector is destroyed by our immune system from the first dose. As for the mRNA, the side effects in the second dose will be more than the first dose. And it will increase even more if it is given many times, such as enlarged lymph nodes. Myocarditis Cross-formulation results in a reduced number of times the mRNA is produced. And the level of immunity is not different. Its effectiveness in reducing severity depends on the number of injections of the vaccine and in practice how complete it is. This means giving at least 3 injections.
10. Getting the vaccine, no matter how many shots It can cause infection. Because vaccines cannot prevent infection, only reduce its severity. Because the incubation period of COVID-19 is very short, only 2 days, the resulting immunity Therefore cannot prevent infection. Therefore there is no divine vaccine. Efficiency as described from the beginning Mostly from short-term studies If followed for a long time, it would be known that infection could not be prevented.
After four years have passed, the majority, or more than 90 percent, of the population has already been infected and has received the vaccine. Emerging immunity of the majority of the population Therefore it is a hybrid immunity. It is relatively complete immunity. The virus has evolved to become less severe. The need to receive a booster vaccine has decreased. The disease has changed to a seasonal disease similar to influenza. and there are better and adequate medicines The virus hasn’t gone anywhere. Practices to reduce the spread of respiratory diseases It’s a useful thing to do. It’s not just COVID-19, it includes other respiratory diseases as well.
