As a long-term outcome of the vaccine has been revealed, here is advice for how often people should be protecting themselves against Covid-19.
All those years ago now, when the UK spent much of 2020 in various degrees of lockdown, Brits were urged to get a jab (and then, following boosters) to help prevent the spread of the virus.
Nowadays, it might not be as common to get the vaccination, but many people still receive boosters for their health.
While a new study has found that the jab did lower the rate of deaths as a result of coronavirus, researchers have also uncovered a link between myocarditis and pericarditis and the vaccine, although it’s very important to note that reports of this are rare.

And the NHS still advises those who ‘need extra protection’ to get vaccinated.
Myocarditis and pericarditis linked to the Covid vaccine
Myocarditis is inflammation of the heart muscle that can often happen after a viral infection. This can develop suddenly, and can recur or be chronic. Most people tend to recover from myocarditis, but for others, if severe, it can lead to a weakening of the heart.
Meanwhile, pericarditis refers to the inflammation of the heart’s lining, and the British Heart Foundation found that while reports are rare, there is a link between these two things and the Covid vaccine.
Scientists found immune signals – CVCL10 and interferon-gamma – may be responsible for the cases of myocarditis, as they could be created in labs when mice were given the vaccines.
The team discovered that blocking the signals with antibodies reduced these symptoms in mice and in structures that mimic the human heart.
Again, though, the event was extremely rare, and the British Heart Foundation also added that the Covid virus was more likely to cause myocarditis than the vaccine itself.
NHS guidance on getting the Covid vaccine
The NHS typically offers the Covid-19 vaccine in spring and early winter to those who need extra protection from the virus, and it is recommended that this be taken.
The vaccines continue to be offered as ‘viruses change and protection fades over time’, as the health service adds: “It's important to top up your protection if you're eligible.”
It recommends the winter Covid-19 vaccine for those aged 75 or over, those between six months and 74 years with a weakened immune system because of a health condition or treatment or those who live in a care home for older adults.
The winter Covid-19 vaccine can be booked through the NHS for those eligible, and the last date to get it is 31 January 2026.
