BY Buddhika Samaraweera  Committees under the Health Ministry are currently considering the administration of Covid-19 vaccine doses on a biannual basis and are analysing the scientific data with regard to such to ascertain its feasibility and necessity, according to the Health Ministry. It was recently reported that certain studies have shown that the effectiveness of the Covid-19 vaccines decreases several months after vaccination and that a biannual vaccine dose will, therefore, have to be administered.  Accordingly, when contacted by The Morning to inquire as to whether the Health Ministry would consider the administration of a biannual Covid-19 vaccine dose any time soon, the Health Ministry’s Communications Director, Public Health Services Deputy Director General and Disaster Preparedness and Response Division Head, Dr. Hemantha Herath said: “A decision has not yet been taken to administer a biannual dose. However, there are committees under the Health Ministry which are looking into these matters and such committees are currently analysing the scientific data with regard to the matter.”  In response to reports that the effectiveness of the Covid-19 vaccines decreases several months after vaccination, Dr. Herath, on an earlier occasion told The Morning that it is more important to adhere to the preventive health guidelines in order to control the Covid-19 pandemic, since it was known from the beginning that the Covid-19 vaccines do not provide 100% protection against the virus. He further said that the contraction of Covid-19 would not be prevented merely because someone has got the vaccines, and therefore urged the public to follow the Covid-19-related health guidelines properly. According to the Epidemiology Unit, as of 8.30 p.m. on 28 November, a total of 29,668,731 Covid-19 vaccine doses have been administered in Sri Lanka, including 2,898,224 doses of the Oxford AstraZeneca Covishield vaccine, 22,868,499 doses of the Sinopharm vaccine, 314,911 doses of the Sputnik V vaccine, 1,999,514 doses of the Pfizer-BioNTech vaccine, and 1,587,583 doses of the Moderna vaccine. In addition, 521,483 Pfizer-BioNTech doses have been administered as booster third doses.
