Since only 40 per cent of eligible Londoners have received their Covid boosters, NHS England is urging more people to get their shot before the end of the month.
The spring booster shot won't be offered under the NHS seasonal scheme after the June deadline.
The immunisation program's execution started in England on April 3, and those who qualified for vaccinations included elderly residents of care facilities, persons over 75, and children over five who were severely clinically vulnerable.
However, according to NHS figures, only 266,000 out of a possible 670,000 London residents have received vaccinations to date.
According to NHS England, 3.6 million people nationwide, more than half of those eligible, have already received a spring booster.
It claimed that more than 240 locations in London and 2,500 locations around England offered booster shots.
When will the spring Covid booster scheme end?
The current Spring Covid booster scheme will end on June 30.
Before then, everyone who qualifies to have the jab has been "strongly" urged to come forward.
The World Health Organisation (WHO) announced last month that Covid-19 is no longer a "global health emergency". The WHO director, however, claimed that the pandemic claimed at least seven million lives.
Who is eligible for the spring booster jab?
If you qualify for a Covid-19 seasonal booster shot this spring, the NHS should have got in touch with you.
The booster shot should be provided to you if you are 75 years of age or older (you must have reached this age on or before June 30, 2023), reside in an elderly care facility or have a compromised immune system and are at least 5 years old.
Those who are at most risk of Covid have been prioritised like previous campaigns.
Levels of protection may deteriorate over time, just like with several other vaccines. By increasing your antibodies, booster doses effectively protect you from developing severe illness or being hospitalised if you contract Covid-19.
