Update knowledge of COVID-19 vaccines
from the workshop of International Coalition of Medicines Regulatory Authorities (ICMRA), which provides technical information on COVID-19 vaccines. and discuss future vaccine directions.
The key points can be summarized as follows:
First, the original vaccine contains the original strain. Although still enough to reduce the risk of serious illness. But its performance deteriorates over time. This is from tracking the changes in the strains of the virus. It was found that the current epidemic virus looks very different from the original strain.
Second, research on the level of immunity from vaccines point out that Adapting the vaccine to a strain corresponding to the epidemic strain will induce greater immunity in the body than the original strain. However, there is no clear information about its protective properties.
The three Omicron subspecies XBB are the main endemic virus strains worldwide. It is genetically very different from the original strain. Therefore, XBB is likely to be a candidate of viral strains that should be used in the production of next-generation vaccines.
Fourth, future booster vaccines should be monovalent vaccines. This is because most people around the world are currently immune to the same strains, both from receiving the original vaccine. and who had been infected before from the past waves
Fifth, monovalent vaccines can also be used as first dose vaccines to immunize people who are not yet immune. Due to the current original species that used to be an epidemic, almost all of them have disappeared Therefore, there should be no need to contain the original species. in future vaccines
Sixth, it is expected that the use of vaccines to immunize people who are not yet immune It may be used in specific populations such as children younger than 4-5 years of age, however, it may vary from country to country. each region of the world based on immune survey data and the past epidemic situation
Seventh, there is a need for a global monitoring mechanism. and decide at the policy level to select different breeds of viruses used to produce vaccines based on complete academic information and most importantly The timing must be considered appropriately. Because it is related to the vaccine industry that takes time to produce. and deliver it to the user.
…above all We must be aware of the current real situation that The global pandemic has not ended. especially in Thailand who still have a lot of infections each day
Vaccines help to reduce the risk of serious illness and death to some degree only.
Most importantly Living a conscious life, not being careless, protecting yourself regularly
be aware that Each infection risks severe illness and death, including long-term Long-term COVID-19.
beware of crowded poor ventilation
avoid eating and drinking Share things with others outside the home.
If we or our family members are sick, we should isolate ourselves and protect ourselves according to the recommended standards. and go for treatment
wearing a mask correctly It will greatly reduce the risk.
