Dr. Yong summarizes 10 points about the COVID-19 vaccine. After having been spoken of badly and was drawn into politics that time has proven that the information stated is correct in every respect
December 26, 2023 Dr. Yong Phuworawan, Head of the Center of Specialization in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University posted on Facebook talking about the COVID-19 vaccine, time will tell.

Dr. Yong stated 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. A crossover formula is injected. and is correct information But there was a lot of slander (bullying) and being 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 as follows:
- 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
- All vaccines are equally effective. It is most effective in the first month after injection, and longer periods of time will not protect against infection. But it is part of reducing the severity of the disease. The efficiency is therefore no different. There is no divine vaccine.
- inactivated vaccine Stimulates immunity as well as natural infection, but lower than viral vector and mRNA vaccines.
- The most commonly used vaccine in the world is the inactivated vaccine, making up more than half of the world’s vaccine doses administered. 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 lower than America and Europe.
- All vaccines can cause complications. 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.
- Inactivated vaccines are much cheaper than mRNA and are easy to store. 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 minus 70 degrees, but inactivated vaccines are kept at 4 degrees in a normal refrigerator. Management is easier. Less wastage
- cross-recipe vaccination It is a solution that makes the final result of the inactivated vaccine have a high level of immunity, such as giving 2 doses of the inactivated vaccine and stimulating it with mRNA. The results It is equivalent to giving 3 injections of mRNA. The information is published in the journal PGH (doi:1080/20477724.2022.2108646) and is accepted worldwide. The World Health Organization also accepts the cross formula.
- Providing cross formulas used in Thailand The first dose gives the dead Sinovac virus followed by the AZ vector virus. Immunity is better than giving 2 doses of the dead virus or 2 doses of the vector virus and is accepted by the World Health Organization.
- Inactivated vaccines have much fewer side effects such as fever and others than with vector and mRNA viruses. AZ vector virus vaccines have many side effects after 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. The effectiveness in reducing severity depends on the number of injections of the vaccine. And in practice, giving the complete amount means giving at least 3 injections.
- No matter how many doses of vaccine you receive, you can become infected. Because vaccines cannot prevent infection. It just reduces the violence. Because the incubation period for COVID-19 is very short, only 2 days, the resulting immunity 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. The immunity that arises in the majority of the population is therefore 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 the flu

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 also includes other breathing diseases as well.
