Booster with Pfizer after 2 Sinovac jabs generates more antibodies, but immunity drops faster

13 Sept 09:27 Key points summarised by AI

A study reveals that two Sinovac jabs followed by a Pfizer booster produce significantly higher initial antibody levels (3,500) compared to an AstraZeneca booster (1,500).
However, the immunity generated by the Sinovac-Pfizer regimen declines faster, dropping from 3,500 to 2,800 within one month, while the AstraZeneca group maintained its 1,500 level over 45 days.
Despite the faster drop, the 1,500 antibody level from the AstraZeneca booster is deemed sufficient to combat the Delta variant, highlighting a trade-off between initial peak response and sustained immunity.

Uthenthawai students and alumni have pledged to cease violent clashes with Pathumwan Institute rivals, coinciding with their campus's reopening after a 90-day closure.
The Minister of Higher Education is mediating the long-running conflict, while the campus closure has significantly disrupted in-person classes and laboratory work for over 1,000 students.
Uthenthawai resists relocation from its current site, citing a historical land grant from King Rama VI, despite Chulalongkorn University's plans to reclaim the land for an educational hub.
Concerns are mounting over the legality of the campus closure, its detrimental impact on uninvolved students, and the potential commercial development of the land, which critics argue contradicts the late King Rama VI's intentions.
