The Wall Street Journal: Covid-19 vaccines and myocarditis link probed by researchers

Some theories focus on the type of spike protein that a person makes in response to mRNA vaccines. The mRNA itself or other components of the vaccines, the researchers said, could also trigger certain inflammatory responses in some people. A new theory under review: inappropriate injections of the vaccine directly into a vein, which sends the vaccine to the heart muscle. To find answers, some doctors and scientists perform tests in laboratory dishes and examine heart tissue samples from people who have developed myocarditis or pericarditis after being vaccinated.

NBC News: Anti-body Covid drugs could protect people with weak immune systems

Even as the Covid Delta Wave ebbs in the United States, millions of people with weakened immune systems remain trapped in anxious limbo and sequestered. A considerable portion of this population, according to research, remains highly vulnerable to the coronavirus even after three or four injections of the vaccine. Many immunocompromised Americans, including people with cancer, autoimmune diseases, and organ transplants, eagerly await what could be their ticket to returning to some semblance of normalcy: the ability to receive periodic injections of long-acting monoclonal antibodies. This, the research suggests, could provide them with substantial protection against Covid-19 that in their case vaccination cannot. (Ryan, 7/11)

The Boston Globe: Pregnant women with COVID-19 face higher rates of serious illness and premature births. Why are they so little vaccinated?

During the last month of her pregnancy last March, Amanda Piantedosi faced a dilemma. Her doctor urged her to get the COVID-19 vaccine. Her husband, parents, in-laws and friends strongly opposed this. Pregnant women infected with COVID-19 face higher rates of serious illness, preterm birth and other complications.

Covid even affects pets –

CIDRAP: Pets also vulnerable to heart complications from COVID-19

Pets are susceptible to the Alpha SARS-CoV-2 (B117) variant and can suffer from serious illness, according to a cat and dog case series published yesterday by UK researchers in Veterinary Record. The study looked at the illnesses of six pets, including four cats and two dogs. All had presented with acute heart disease, including severe myocarditis. Animals tested positive for the Alpha variant or had antibodies 2-6 weeks after illness. Many owners had been sick with COVID-19 before their pets got sick. (11/5)
