SINGAPORE-The Singapore government announced on Wednesday that if the booster vaccine is not vaccinated, Singaporeans will lose their fully vaccinated status after 270 days.

The Ministry of Health of Singapore said in a press release that the protective effect of the primary series of vaccines was weakened and “substantially reduced six months after the last vaccination.”

This policy will take effect on February 14, 2022.

Southeast Asian countries are not the first to adopt such measures. Since October, Israel and Bahrain have also implemented similar policies.

In December last year, Dr. Anthony Fauci, a top infectious disease expert in the United States, told CNBC that The definition of full vaccination may change.

The ministry stated that the booster can enhance protection against infections and serious diseases of omicron variants. According to the national vaccination plan, approximately 87% of the total population of Singapore received two injections, and 42% of the population received booster injections.

The fully vaccinated status will expire in about 9 months, but Singapore recommends that people 18 years and older receive a booster injection after 5 months.

The press release said: “Persons 18 years and older who have completed the primary vaccination series should receive a booster dose of mRNA vaccine no later than 270 days after the last vaccination of the primary vaccination series.”

This means that people who choose non-mRNA vaccines will need to receive mRNA injections as a booster.

However, the press release indicates that Novavax’s non-mRNA vaccine may be available as a booster vaccine before the deadline.

“For this group, most people will not be [boosters] It’s been a while,” the Ministry of Health said. “We expect that by then they will have the option of using the non-mRNA vaccine Novavax vaccine. “

People receiving non-mRNA vaccines in Singapore must get three doses as part of the primary vaccination series.

The first two injections are 21 days apart, and people are eligible for the third injection three months after the second injection. The fully vaccinated status will expire 270 days after the third vaccination.

Novavax has not yet been approved for use in Singapore, but Kenneth Mak, director of medical services at the Ministry of Health of Singapore, told reporters that he is optimistic that it will be authorized.

“We expect it to play an important role as a non-mRNA vaccine alternative to promote population growth,” he said in the briefing, adding that compared to other non-mRNA vaccines, it shows better effects on delta and omicron. Already used in Singapore.

He said that once the expert committee completes its discussions, it will provide more details on using Novavax as a booster.

Health Minister Wang Yikang stated that Singapore hopes to “provide a good combination of vaccines for our national vaccination program, including both mRNA and non-mRNA.”

He said that the inclusion of Novavax will “be consistent with the attitude we have always maintained”.

U.S. Travel Advisory

Ong also talked about The CDC decided to update Singapore’s Covid level to “unknown”.

The announcement was updated on Tuesday and told travelers to avoid going to Singapore.

The Centers for Disease Control and Prevention added: “Since Singapore’s current situation is unknown, even fully vaccinated travelers may be at risk of infection and transmission of COVID-19 variants.”

The Ministry of Health of Singapore “is working with the US Embassy and the US Centers for Disease Control and Prevention to provide them with the necessary data. To be clear, we know our situation very well,” Wang said.

He said that the CDC “does not know our monitoring test numbers”, including 150,000 polymerase chain reaction tests (with a positive rate of less than 2%) and 145 wastewater test stations per week.

He said: “We are convinced that the incidence of Covid-19 in our community is currently low and stable.”

Clarification: This story has been revised and the number of wastewater testing stations has been updated.
