Two doses of the Pfizer-BioNTech/ Comirnaty and Moderna COVID-19 vaccines are required to achieve optimal protection against COVID-19. If it is a single dose, what will the efficacy be? MOH will continue to monitor and review further data on the duration of immunity. Updated data from the Pfizer-BioNTech/ Comirnaty and Moderna Phase 3 trials on individuals with a follow-up time of at least six months showed that the vaccines continue to be effective for at least six months with no signs of waning protection.
The coctail of antibiotics for mac have to be taking 3 times a week?? trial#
How effective is the vaccine? How long does the protection last?īased on Phase 3 trial data from Pfizer-BioNTech/ Comirnaty and Moderna, the efficacy of the vaccines in preventing symptomatic COVID-19 disease, after completion of the vaccine regimen, is about 95%. This further supports that scientific rigour was not compromised in the development of the mRNA COVID-19 vaccines. Safety, scientific or ethical integrity have not been compromised, and no short-cuts have been made, but the unique circumstances and factors described above have allowed accelerated development.Įmerging real-world and follow-up data on the safety and effectiveness of the mRNA vaccines in other jurisdictions is consistent with the effectiveness of the mRNA COVID-19 vaccines observed in the Phase 3 trial data. Many trials have performed their trial phases concurrently, allowing for sufficient data to be produced in a shorter time. Given the pandemic situation, recruitment for and conduct of the randomised controlled trials to identify the differences in disease risk between those given vaccines and placebo, are able to be conducted more quickly than in the absence of a pandemic.ĭ. Strong global partnerships between many different partners including international organisations, governments, researchers and manufacturers Ĭ. Significant investment and dedication of resources from vaccine manufacturers to the ramping up of vaccine production moreover, the mRNA technology platform had already been in development for many years prior to the COVID-19 pandemic.ī. How can we be sure that scientific rigour has not been compromised?Īn accelerated development timeline for vaccines against COVID-19 was possible given the following:Ī. Vaccines for COVID-19 have been approved for use in a shortened timeframe compared to other vaccines or drugs. Second COVID-19 Vaccine Authorised for Use in Singapore HSA Grants Interim Authorisation for Moderna COVID-19 Vaccine in SingaporeĤ.
Government Accepts Recommendations of Expert Committee on COVID-19 Vaccinationģ. Expert Committee Submits Recommendations on Singapore’s COVID-19 StrategyĢ. Only vaccines deemed suitable for use in target population subgroups, and where overall benefits outweigh the known risks, are recommended for use by the Expert Committee.ġ. The Expert Committee on COVID-19 Vaccination (EC19V) has also recommended the use of the Pfizer-BioNTech/ Comirnaty and Moderna COVID-19 Vaccines by the population, and are the 2 vaccines used in the national vaccination programme*. HSA has authorised their use locally under the Pandemic Special Access Route (PSAR) which facilitates early access to vaccines and medicines during a pandemic, such as COVID-19. The Health Sciences Authority (HSA) has assessed that the Pfizer-BioNTech/ Comirnaty and Moderna COVID-19 Vaccines meet safety and efficacy standards. Which vaccines are approved for use in Singapore? Which of these vaccines are included in the national vaccination programme?
