Initially, it was decided that the second dose of the covid vaccine should be given to those who were given the first round in 4 weeks, but later it was postponed to 12 weeks and then again to 14 weeks. The director of the Epidemiological Unit speaking on behalf of the government has stated that such postponement of administering the second dose would not be harmful.<\/p>\n\n\n\n
The director Dr. Sudath Samaraweera has stated this to the Lankadeepa newspaper published today (29). According to him, the second vaccination has been given to those who received the first vaccine. Following is the full text of the Director’s comments in this regard.
\u201cThis is something we need to look at scientifically. For a person to be fully immunized against coronavirus, two vaccines must be given. Despite having Immunization from the first vaccine, after about 12 weeks, it gradually disappear. Then the antibodies in the blood decrease. However, if we are exposed to the virus again the memory stored in our cells will produce antibodies again through that memory.
But the process is a bit slow. This is why we give a second vaccine. The best time to fully immunize after the first vaccine was initially found to be 4 weeks, but later changed to 12 weeks. The government decided to give the second vaccine between 10 and 12 weeks, but due to avoid side effects, it was decided to be given after 14 weeks.\u201d<\/p>\n
