A previous coronavirus infection does not fully protect young people from re-infection, research shows.
The researchers said that despite a previous infection and the presence of antibodies, vaccination is still needed to boost immune responses, prevent reinfection and reduce transmission.
They added that young people should get vaccinated whenever possible.
Although the study looked at young, healthy, predominantly male recruits, the researchers believe the risk of reinfection will apply to many young people.
Professor Stuart Sealfon, Icahn School of Medicine in Mount Sinai, New York, and lead author of the study, said: “As vaccine deployments continue to gain momentum, it is important to remember that, despite a previous infection with Covid-19, young people can catch the virus again and can still transmit it to others.
“Immunity is not guaranteed by a past infection, and vaccines that provide additional protection are still needed for those who have had Covid-19.”

‘Many more will die here’
President Rodrigo Duterte said he was uncertain whether the Philippines could get adequate vaccines against Covid-19, while warning that more people will die and “the worst of times” are yet to come.
Mr Duterte said his administration had done its best despite criticism and could use back-up power, for example, to take over hotels if the shortage of rooms in hospitals worsens. But he said rich countries are in control of the vaccine supply and there is little other countries can do but wait.
He said, “There are not enough reserves to inoculate the world. It will take a long time. I tell you many more will die here.”
The Philippines has received more than three million doses of Sinovac and AstraZeneca vaccines, most of which were donated by China and as part of the World Health Organization’s COVAX arrangement.
The government aims to purchase at least 148 million doses to inoculate about 70 million adult Filipinos, but the plan has encountered supply problems and delays.
Security fears could see Taiwan getting rid of AstraZeneca jabs
Taiwan’s health authorities have admitted they may have to dispose of AstraZeneca Covid-19 vaccines due to public reluctance to receive the vaccine, The telegraph Asia correspondent Nicola smith reports below:
To date, Taiwan has received 117,000 doses of the vaccine directly from AstraZeneca, with an expiration date of June 15, and 199,200 of the same brand supplied through COVAX, which are due to expire on May 31.
However, only 28,465 of its nearly 24 million inhabitants have been vaccinated.
Chuang Jen-hsiang, a senior official with the Centers for Disease Control, said authorities have been instructed to ask vaccine manufacturers to extend their shelf life.
In the worst-case scenario, the expiration date would be unalterable and the vaccines scrapped, he said, according to the Taipei Times.
The reluctance has been attributed to safety fears after reports of European countries halting deployment of the vaccine despite its approval by the World Health Organization.
The reluctance was also fueled by a lack of urgency in Taiwan, which stopped the community spread of Covid-19 last April thanks to strict quarantine requirements and border closures.
It has so far recorded just 1,069 cases and 11 deaths from the virus.
Patients must wait at least a year to receive hospital care
Nearly one in 10 patients requiring hospital care faces a wait of more than a year, according to figures which reveal Covid’s toll on the NHS.
At least 387,885 people had been waiting for more than 52 weeks in February, a 240-fold increase from the previous year, when the number was 1,613, the data showed.
Health experts said it would take years for the NHS to return to normal service levels, adding that the backlog could worsen, even if pressure from the virus eases, as patients with long-lasting illnesses that have faced the house over the past year are beginning. go back to the hospital.

Lockdown restrictions continue to ease in Scotland
Some coronavirus-related travel restrictions have been lifted in Scotland and more people can now meet outside.
The latest step in easing the lockdown was announced during an unscheduled Covid-19 briefing by Prime Minister Nicola Sturgeon on Tuesday.
She said the continued decline in virus cases meant restrictions could be relaxed sooner than expected.
From Friday, Scots can cross local government borders to socialize in the open air, have fun and exercise.
But they must follow the “stay local” order for other purposes such as non-essential purchases, and travel to certain islands is not allowed.
Rules for gatherings have also been relaxed, with groups of up to six adults from six households now allowed to meet outside.
Children under 12 do not count towards the limit.
Half of Heathrow’s passport control booths unused
Chaotic queues of up to six hours at Heathrow are made worse by the fact that half of passport control booths are unused due to a lack of plexiglass screens, a union has said.
The lack of side screens means half of the 40 offices are not monitored because border staff cannot work alongside each other, according to Lucy Moreton, professional officer for immigration and border officials of the ISU.
The problem emerged amid growing complaints about queues for arrivals at the airport which last on average between two and six hours.
