3-8 weeks between 1st and 2nd COVID vaccinations
    2021-04-08  08:53    Shenzhen Daily

CITIZENS who get the first COVID-19 vaccine shot are expected to get their second round after 14 to 28 days. But what happens if someone misses that timeframe by a day, a week or even longer?


The municipal health commission said those who have received the first shot of the COVID-19 vaccine shouldn’t worry about the possibility of not being able to get the second shot exactly 14 to 28 days after the first, because the second dose can be administered within the recommended three- to eight-week window.


According to the city’s health authorities, after the first dose of the COVID-19 vaccine, the patient should wait at least three weeks, and then the second dose should be completed, as soon as possible, before eight weeks have passed, Shenzhen Economic Daily reported.


Relating to concerns that the vaccine may have a protection period of only half a year, the National Health Commission recently announced that the antibody level of vaccine recipients has currently been monitored for more than six months.


However, that does not mean that the vaccines will only offer immunity against COVID-19 for six months. Additionally, antibodies are not the sole indicator of protection, said the national health authorities.


Afterall, humans have only been exposed to the novel coronavirus for little more than a year, and the time since the release of the COVID-19 vaccines has been even shorter. Therefore, the current research on the duration of effectiveness for the vaccines is still under observation.


Shao Yiming, a researcher with China Center for Disease Control and Prevention, said that for people who have temporary or urgent tasks to handle in a pandemic-hit area but do not have enough time to wait, it is more suitable for them to inject the single-dose adenovirus-vectored vaccine.


But the protection efficiency of an adenovirus-vectored vaccine may decrease when the novel coronavirus has mutated in later stages.


It is highly suggested that citizens make decisions in accordance with their own personal needs and the latest local COVID-19 data.
