What you need to know about Singapore's new Covid-19 vaccination strategy

The Ministry of Health (MOH) on Friday said Singapore was transitioning to a new strategy for Covid-19 vaccinations, with a focus on being up to date, rather than based on the total number of shots received.
At the same time, the Government has lifted all remaining vaccination-differentiated measures, including removing the requirement for vaccination for events with more than 500 participants or dining in at eateries.
What does this mean for those who are thinking of whether or not to get a second booster? The Straits Times has the answers.
Q: HOW MANY DOSES OF A COVID-19 VACCINE AM I NOW REQUIRED TO TAKE?
Singapore now requires that people get two shots of an mRNA vaccine, with a booster dose administered at least five months after completing the primary series.
As part of a new approach, vaccination is based on being up to date, rather than on how many doses someone has had, similar to how influenza vaccinations are administered seasonally, MOH said on Friday.
Under this strategy, people will still have to get three doses of an mRNA vaccine for basic protection.
Also, those 50 and older - including those who have taken a second booster - should receive a booster shot between five months and a year from their last dose.
People will be considered up-to-date with their Covid-19 vaccinations if they have at least the minimum protection and their last vaccine dose was within the past year.
Q: WHAT ARE BIVALENT VACCINES AND WHO SHOULD TAKE THEM?
The Moderna bivalent vaccine approved by the Health Science Authority (HSA) in September targets the original Sars-CoV-2 strain of the virus as well as the Omicron BA.1 variant.
At the time, HSA said preliminary data suggested that the Moderna bivalent vaccine was also effective against the Omicron BA.4 and BA.5 variants, and others such as the Delta and Gamma variants.
The Expert Committee on Covid-19 Vaccination has recommended the use of the bivalent vaccine to replace the existing formulation.
This means the original Moderna Spikevax vaccine will be replaced with the bivalent version starting on Oct 14, and made available for people 18 and above.
People 50 or older, as well as those who have yet to get basic protection against Covid-19, should have the bivalent vaccines, MOH said.
Pzifer's bivalent vaccine is still under evaluation, but is expected to be available in Singapore by the end of the year.
Q: I HAVE ALREADY TAKEN MY PRIMARY SERIES OF TWO MRNA JABS AND A BOOSTER SHOT. DO I STILL NEED TO GET ADDITIONAL SHOTS OF THE COVID-19 VACCINE?
A study by the United States Centers for Disease Control and Prevention, published in February, showed that the effectiveness of mRNA boosters declined substantially after four months, suggesting the need for additional shots.
With new variants of the coronavirus expected to emerge with the approaching winter in the northern hemisphere, Health Minister Ong Ye Kung said those eligible should get their shots.
MOH now recommends that only those 50 and above get a booster shot between five months and a year from the last dose, but it added that it will consider extending this recommendation to other age groups at a later date.
Q: WILL NON-MRNA VACCINES STILL BE AVAILABLE?
The Novavax/Nuvaxovid vaccine remains available at the joint testing and vaccination centre in Bishan, as well as the Yishun and Jurong polyclinics.
The Sinovac-CoronaVac vaccine was earlier available as a booster only for those medically ineligible to receive the mRNA and Novavax/Nuvaxovid vaccines.
Now, people who have yet to receive a booster dose can be given the Sinovac vaccine as a booster, even if they are not medically ineligible for other vaccines.
However, the Expert Committee on Covid-19 Vaccination still recommends they consider taking either the mRNA vaccines from Moderna and Pfizer-BioNTech or the Novavax vaccine as a booster due to the better protection conferred.
