Is it worth getting a second COVID-19 booster?

13 Sept 09:27 Key points summarised by AI

While Thailand actively promotes a fourth COVID-19 jab, the World Health Organization (WHO) has yet to recommend it universally, citing a lack of comprehensive evidence.
Medical experts, including Thai virologist Dr. Yong Poovorawan, strongly advise a fourth dose for high-risk groups such as individuals over 50, those with chronic illnesses, and medical personnel, to prevent severe infections.
Guidelines suggest receiving the fourth jab 3-4 months after the third, depending on the type of vaccine previously administered (inactivated vs. viral vector).
Some experts express skepticism about the fourth dose's broad efficacy, noting that immunity may wane quickly and new variants could reduce the effectiveness of current vaccines, leading several countries to limit it to vulnerable populations.
