A booster shot provides the same level of immunity against Covid-19 to people whose first two shots have been either inactivated or mRNA vaccines, a top virologist said.

The fourth Covid-19 jabs of AstraZeneca, Pfizer and Moderna vaccines offer similar protection against Omicron, a study by the Department of Disease Control on Chiang Mai residents showed.

The Central Vaccination Centre announced on Thursday that people can start registering for a Pfizer or Moderna booster shot from Friday onwards.

The FDA said that rates of hospitalization and death due to COVID-19 among children under 5 were higher than among those aged 5 to 17, "underscoring the benefit of an effective COVID-19 vaccine in this age group."

Data from 79 real-world studies show that AstraZeneca and mRNA Covid-19 vaccines provide equal protection against hospitalisation and death after two doses, several experts said on Wednesday.

Covid-19 booster shots will be given to 12 to 17-year-olds when schools reopen next month, the Department of Disease Control (DDC) said on Sunday.

Half the dose of an mRNA vaccine can provide as much immunity as a full dose, a top virologist said recently.

The French ambassador to Thailand on Monday handed over 3.2 million doses of the Pfizer Covid-19 vaccine to Prime Minister Prayut Chan-o-cha.

SINGAPORE - A booster shot with the Moderna vaccine offered older people better protection against Covid-19 if they had previously taken Pfizer jabs, researchers at the National Centre for Infectious Diseases (NCID) have found.

It is not necessary to give children an inactivated and mRNA vaccine cocktail because two doses of an mRNA vaccine provide plenty of protection, Somsak Lolekha, president of the Paediatric Society of Thailand, said recently.

A cocktail of Sinovac and Pfizer Covid-19 vaccines was approved by the Public Health Ministry’s Immunity Promotion Subcommittee for children aged 12 to 17.

The first batch of orange-cap Pfizer vaccines for children aged 5-11 years was delivered to Thailand on Wednesday morning, Department of Disease Control director-general Dr Opas Karnkawinpong said on Thursday.
