    By Mary Van Beusekom

    One study of 2-dose vaccination with Pfizer/BioNTech and Moderna mRNA vaccines found significantly diminishing efficacy against infection in nursing home residents, while two other studies showed sustained protection against coronavirus-related hospitalizations but declining coverage against new adult cases.

  • COVID-19Studies Look at COVID-19 Vaccines-Connected Clotting, Myocarditis

    By Lianna Matt McLernon

    Two studies published by JAMA Cardiology Tuesday discuss adverse effects associated with COVID-19 vaccines. Despite these risks, both research teams continue to advocate for COVID-19 vaccines as the health risks from the virus are far greater than those linked to the vaccine.

  • VaccinesWhy We Need to Talk Openly about Vaccine Side Effects

    How can health authorities and politicians help ensure public acceptance of vaccines which, their rare side effects aside, have proven effective in preventing serious Covid-19 disease? The best way to do this is to talk openly about all aspects of the vaccines, including potential negative aspects such as side effects.

  • SmallpoxFDA Approves Drug to Treat Smallpox

    The U.S. Food and Drug Administration last week approved Tembexa (brincidofovir) to treat smallpox. Although the World Health Organization declared smallpox, a contagious and sometimes fatal infectious disease, eradicated in 1980, there have been longstanding concerns that the virus that causes smallpox, the variola virus, could be used as a bioweapon.

  • VaccinesEvaluation of Safety Studies Affirms That Vaccines Are Safe for Children and Adults

    A new study looking across a large body of research finds further evidence for the safety of vaccines that are Food and Drug Administration–approved and routinely recommended for children, adults, and pregnant women.“These findings support decisions to vaccinate to protect ourselves and our communities from a variety of diseases,” said one expert. “This research is an important reminder that vaccines are safe and any risk they may pose is far outweighed by their ability to protect against diseases.”

  • Truth decayJust 12 People Are Behind Most Vaccine Hoaxes on Social Media

    Researchers have found that just twelve individuals are responsible for the bulk of the misleading claims and outright lies about COVID-19 vaccines that proliferate on Facebook, Instagram and Twitter. Many of the messages about the COVID-19 vaccines being widely spread online echo the lies peddlers of health misinformation have been spreading in the past about other vaccines, for example, the vaccines against measles, mumps, and rubella.

  • Truth decayHow Truth Decay Is Fueling Vaccine Hesitancy

    By Jennifer Kavanagh

    A recent poll found that more than a quarter of Americans will not try to get vaccinated. Why are so many people opting out? Why are so many people opting out? The reasons vary, but some simply don’t trust the public health and government officials who are urging them to get the vaccine. The spread of misinformation and disinformation, which is rampant over social media, is one of the factors fueling vaccine hesitancy. And in turn, it’s threatening our ability to end the pandemic for good.

    By Steve Baragona

    The results of a new poll show that vaccine hesitancy worldwide poses a risk to ending the COVID-19 pandemic for good. In 79 out of 117 countries surveyed, the number of people who said they were willing to be vaccinated was below 70%, the minimum percentage of the population that scientists say needs to have immunity to stop the virus from circulating. 

  • VaccinesA Third of Americans Say They Are Unlikely or Hesitant to Get COVID-19 Vaccine

    News reports indicate COVID-19 vaccines are not getting out soon enough nor in adequate supplies to most regions, but there may be a larger underlying problem than shortages. A new study found that more than a third of people nationwide are either unlikely or at least hesitant to get a COVID-19 vaccine when it becomes available to them.

    As the first COVID-19 vaccines are being administered across the United States—developed, tested, and approved with historic speed—countless questions have arisen about what comes next. Is one vaccine better than another? Can the United States both speed up inoculation and overcome some people’s hesitance to get the shot?

    As the world watches how U.K. residents respond to COVID-19 vaccinations, three leading experts on the virus are urging Americans and the U.S. government to be vigilant against anti-vaccination advocates and their “rumors, misinformation, and conspiracy theories in a fractured media universe.”

  • VaccinesPfizer’s Ultra-Cold Vaccine Could Be Difficult to Distribute

    By Michael Head

    The excitement that greeted the news of a vaccine candidate that may be highly effective against COVID-19 was indeed something to behold. One complicating factor will be the maintenance of the cold chain. Vaccines are fragile products: they need to be stored at specific temperatures, and some are sensitive to light and need to be transported in dark glass vials. These precise conditions must be maintained throughout the vaccine journey, right until the point when you’re in the GP surgery with your sleeve rolled up and the nurse opens the fridge door to extract the required immunization.
