Doctor Yong Phuwarawan, Head of the Center of Excellence in Clinical Virology at Chulalongkorn University, has emphasized that getting infected with COVID-19 for the third time is not uncommon. This comes after a candidate for the upcoming election, Mr. Phitha Lim Chareonrat, tested positive for COVID-19 even after receiving six doses of vaccination and coming into contact with the virus for the third time.
Dr. Yong took to Facebook to clarify that bruising infections are not uncommon in most strains of COVID-19 where the XBB strain is found. He also mentioned that COVID outbreaks are seasonal, with the virus expected to continue spreading until July and August, before starting to decrease in September.
The dominant strain currently identified is the Duangkaew strain XBB.1.16, and almost all of the identified strains are XBB. However, the immunity caused by past vaccinations, including those for the Wuhan species and two strains of BA.5, was found to be ineffective in preventing infection with the XBB strain.
Dr. Yong’s study of 250 people also revealed that the severity of recurrent infections was much less than the first infection. He compared this to influenza, where strains can change and cause new infections. Similarly, when the species of COVID-19 changes, it can result in new infections. However, the main immunity provided by vaccines is enough to protect and reduce the severity of the infection, but it does not prevent infection entirely.
Looking towards the future, Dr. Yong emphasized the need for predictive vaccination, similar to the flu. He mentioned that vaccine companies are advised by the World Health Organization to produce vaccines targeting the XBB strain. However, the production process takes at least six months, and by that time, the virus may have changed its species again, making it difficult to keep up with the evolving strains.
Dr. Yong also highlighted the positive aspect of the study, stating that the mutation rate of COVID-19 has slowed down compared to the early stages of the pandemic. The mutation rate currently ranges from 1.2 to 6.7 vacancies per thousand per year, which is similar to influenza A. This suggests that the trend of the virus may become closer to influenza A in the future.
As the COVID-19 pandemic continues to evolve, it is crucial to stay informed about the latest developments and follow recommended guidelines to protect oneself and others from the virus.
What is the likelihood of experiencing severe illness after getting infected with COVID-19 post-vaccination compared to being unvaccinated?
Getting infected after vaccination is still possible, although it is less likely to lead to severe illness.
Dr. Yong’s statements were made in response to the case of Mr. Phitha Lim Chareonrat, who was infected with COVID-19 despite receiving six doses of vaccination and coming into contact with the virus for the third time. This case raised concerns about the effectiveness of the vaccines and the possibility of reinfection.
Dr. Yong explained that in the XBB strain of COVID-19, which is prevalent in many areas, including Thailand, bruising infections are not uncommon. He emphasized that getting infected for the third time is not surprising, as the virus can mutate and evade the immune response, making it difficult for vaccines to provide complete protection.
However, Dr. Yong also noted that while breakthrough infections can occur after vaccination, they are usually milder and less severe than infections in unvaccinated individuals. Vaccines help boost the immune system and reduce the risk of severe illness, even if a person still gets infected.
He urged the public to continue following preventive measures, such as wearing masks, practicing good hand hygiene, and maintaining social distancing, alongside vaccination. These measures can further reduce the risk of infection and transmission.
Dr. Yong’s remarks highlight the importance of understanding the limitations of vaccines and the ongoing need to take precautions, even after vaccination. The case of Mr. Phitha Lim Chareonrat serves as a reminder that while vaccines offer protection against COVID-19, breakthrough infections can still occur, particularly with the emergence of new strains.
