A fourth dose of the Pfizer/BioNTech or Moderna vaccine provides increased protection from covid-19, according to a study.
A fourth dose of the covid-19 vaccine could provide a substantial boost in the amount of immune cells in the body, according to a study conducted as part of the University ofSouthampton's Cov-Boost vaccine trial.
There is a fourth vaccine available for people who are 75 and over. A larger group of people in the UK may be offered a second booster jab later this year.
166 participants who had received a third dose of the Pfizer/BioNTech vaccine were either given a full dose of Pfizer/BioNTech or a half dose.
The results show that the fourth jab offered higher levels of protection than a third jab and was particularly effective for people over the age of 70.
Some participants in the study maintained higher levels of immunity after a third dose and only received a small boost from a fourth jab, suggesting there could be a ceiling to the immune response.
The ceiling effect could suggest that a fourth booster shot is less effective in people with a shorter window between their third and fourth vaccine doses.
Saul Faust said in a statement that the results show the benefits of the most vulnerable people receiving current spring boosters.

There was a small but significant increase in loneliness worldwide because of Lock Downs and social distance caused by the Pandemic, according to a meta-analysis of 34 studies.
The dire warnings about aloneliness may be overblown, according to Mareike Ernst, of Johannes Gutenberg-University Mainz in Germany. As loneliness is a risk for premature mortality and mental and physical health, it should be closely monitored.
The Office for National Statistics (ONS) said that 51 percent of people who tested positive for covid-19 were following isolation guidelines in England.
The legal requirement to self-isolate after a positive covid-19 test was removed in England. In April, new isolation guidance was issued for those who tested positive, urging them to avoid contact with other people until they felt better. The rest of the UK has similar guidance.
The proportion of people who were positive for covid-19 who followed self-isolation was similar to what we reported.

According to a WHO report, the covid-19 epidemic caused more than 13 million deaths.
The WHO calculated the number of deaths caused by the Pandemic in the period from 1 January 2020 to 31 December 2022.
National death data for each country was combined with statistics from scientific studies in the same country. They used a statistical model to account for deaths that may have been overlooked.
The team estimated the number of deaths that would have been expected had the epidemic not occurred.
The excess includes deaths caused by the swine flu, as well as deaths caused by healthcare systems being overwhelmed.
Over 6 million people have died of covid-19 worldwide, not taking into account the indirect deaths.
The impact of the Pandemic and the need for all countries to invest in more resilient health systems that can sustain essential health services during crises are both shown by the data.

A study suggests that more than one in 10 people could have severe neurological symptoms.
More than 16,000 people were hospitalized with covid-19 in 24 countries between March 2020 and March 2021. Nearly 13 per cent of the participants developed a serious neurological condition, like a stroke, seizure or encephalopathy, an umbrella term for disease that alters the brain's function or structure.
If you fight off the SARS-CoV-2 virus, you may be able to boost your protection against other coronaviruses.
In a small study, scientists at Scripps Research in the US found that people who had recently fought off the coronaviruses reacted more strongly to spikes in their own genes than people who had not.

The natural cognitive decline that occurs between 50 and 70 years old is what may cause people to lose 10 IQ points.
Covid-19 can cause long term cognitive and mental health issues. Researchers at the University of Cambridge analysed 46 people who were hospitalized due to the problem between March and July 2020.
Six months after their initial illness, the participants underwent cognitive tests. More than 66,000 people from the general population were compared with these results.
Those who were hospitalized with covid-19 scored worse on verbal analogical reasoning tests.
Slower processing speeds were also recorded. The part of the brain responsible for attention, complex problem-solving and working memory is believed to be less efficient after covid-19.
The researchers said that any recovery was gradual and that scores and reaction speeds improved over time.
This cognitive impairment probably has many causes, including inadequate blood supply to the brain, blood vessel blockage, and damage caused by an overactive immune system, they said.
Around 40,000 people have been through intensive care with covid-19 in England alone and many more will have been very sick, but not admitted to hospital, according to Adam Hampshire at Imperial College London.
There is a large number of people who are still having problems with their cognitive function many months later.

The Murdoch Children's Research Institute in Australia may have discovered the biological mechanism behind the rare and severe covid-19 response seen in some children.
Doctors have not been able to figure out why some children develop multisystem inflammatory syndrome in response to covid-19, which can cause symptoms such as abdominal pain and heart disease.
After analyzing the blood of 33 children with the condition, the researchers identified 85 proteins that were specific to the condition, potentially opening the door to new treatments.
According to a study of more than 61,000 people with asthma in the US, Covid-19 may make asthma worse. The participants who tested positive for covid-19 had more asthma-related hospitalisations, emergency inhaler use and steroid treatments in the six months after the infections, compared with the participants who did not test positive.
People with asthma are affected by covid-19. A study published in November 2020 found that people with asthma may be less likely to develop covid-19.
