Doctor of Chulalongkorn University reveals that people who are infected with covid have been vaccinated with hybrid immunity. indicates that the future must be boosted every year like influenza
On July 31, 2022, reporters reported that the latest Prof. Dr. Yong Phuworawan Royal Graduate and Head of the Center specializing in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Facebook post to educate about COVID-19 on issues when the virus mutates Or change the species that the Covid-19 virus is an RNA virus, so there is a mutation. Or it is easier to change genetics than viruses in the DNA group, and when a vaccine is used to pressure the virus naturally, the principle of evolution It causes a genetic mutation to avoid the immune system occurring. especially the immunity in the part that prevents infection Immunity in virus removal or the cure of the disease is still there thus reducing the severity of the disease
Vaccines in use have been developed since the original Wuhan strain. The virus has come a long way. Therefore, the effectiveness in preventing infection is reduced. But eliminating the infection or reducing the severity still exists. to prevent infection the desired immunity If the virus strain will protect well even with low
Prof. Dr. Yong stated that People who are infected and have been vaccinated or infected and vaccinated It has a relatively high immunity. “Hybrid immunity”
“And if it’s the immunity to the latest strain in the outbreak right now? those who have been infected Therefore, it is like getting an excellent syringe vaccine that matches the infected strain. if infected with the latest strain It will protect well in the latest species. People who have been infected since the Wuhan strain, or two years ago, are still likely to be reinfected.
The strains contained in the vaccine are therefore important. Developing a vaccine to change the strain to match the existing strain. and using it quickly, it is necessary for that reason. The future of the COVID-19 vaccine is similar to the flu Must be modified to match the species that are spreading. and will be injected in the risk group and give annually like influenza vaccine,” said Prof. Dr. Yong.
