Vaccinations against other diseases give immunity from COVID-19: a list
As U.S. leaders work to control the spread of the coronavirus, researchers around the world are working to unravel the mysteries that remain around the infection. Writes about it KSL.
One of these mysteries is why the disease can be so different in different people. One expert says the answer may lie in looking at previous vaccinations they received.
“When we studied the situation with the spread of the COVID-19 disease, we found that people who were previously vaccinated from pneumococcus, flu, hepatitis and others - had a lower risk of infection, ”said Dr. Andrew Badley, an infectious disease specialist at the Mayo Clinic.
According to Badley, this is what immunologists call immune training: how your immune system creates an effective response to fight infections.
“It's a good analogy to think of your immune system as a muscle,” he said. "The more you train this muscle, the stronger it will be when you need it."
There is no conclusive evidence that any other vaccines increase immunity against COVID-19. But some researchers have suggested that this is possible.
In June, a US research team proposed giving people a booster dose of the vaccine against measles, mumps and rubella (MMR)to see if it helps prevent the most serious consequences of coronavirus infection. And in July, researchers found that in countries where many people were introduced anti-tuberculosis vaccine Bacillus Calmette-Guerin (BCG), deaths from coronavirus are lower, and this finding is consistent with other studies suggesting that the vaccine may boost immunity in people in general.
Dr. Monica Gandhi, an infectious disease specialist at the University of California, San Francisco, is working with a team of researchers to understand how more people can survive COVID-19 with minimal or no symptoms. According to the US Centers for Disease Control and Prevention, about 40% of people infected with the virus have no symptoms.
Gandhi's team found that wearing masks mattered in this.
“Masks really reduce the amount of virus that you catch,” she said.
The average number of new cases per day in the United States is over 54, compared with more than 000 per day in mid to late July.
However, the average daily mortality rate from COVID-19 has hovered above 1000 for over two weeks. Prior to that, the country had been below this level for seven consecutive weeks.
According to a recently published study, up to 80% of Americans would be infected with COVID-19 if states did not enforce physical distancing policies.
Researchers at Harvard University and University College London found that every state in the United States adopted at least a measure of physical distancing in March to slow the spread of the pandemic.
According to a study published in the journal PLOS, this policy resulted in the aversion of more than 600 cases in just three weeks.
“The results show that isolation orders have reduced both cases of illness and death. These measures work, and policymakers should use them to cope with localized epidemics, ”said Dr. Mark J. Zidner, study co-author at Harvard Medical School and an infectious disease physician at Massachusetts Hospital.
The study says that deaths fell 2% per day, starting a week after the start of the physical distancing policy.
The incidence of the disease in nursing homes has increased due to the spread among the population. The incidence of COVID-19 in US nursing homes rose rapidly in July after a steady decline in June, indicating a serious risk for a particularly vulnerable group of people.
According to the American Health Association and the National Center for Life Assistance, the rise in nursing home cases was driven by an overall rise in cases in the general population and should prompt the US government to take protective measures.
“We need public health officials to focus on reducing the spread of infection, including personal protective equipment, testing and staff support,” wrote Mark Parkinson, CEO of AHCA / NCAL.
New weekly COVID-19 cases in nursing homes fell from 9072 at the end of May to 5468 by June 21, but then rose to 8628 in the week of July 19.
The report said this confirmed fears that the number of cases will rise in nursing homes as the number increased across the country from June to July.
The CDC states that older adults and people with certain underlying medical conditions are at increased risk of severe illness.
