Preliminary findings from two vaccine safety monitoring systems suggest a higher-than-expected number of cases of heart inflammation after the second dose of mRNA Covid-19 vaccines in young men, the U.S. Centers for Disease Control and Prevention (CDC) said on June 10.

The U.S. Food and Drug Administration approved Pfizer Inc.’s Prevnar 20 (Pneumococcal 20-valent Conjugate Vaccine) for the prevention of invasive disease and pneumonia caused by the 20 Streptococcus pneumoniae (pneumococcus) serotypes in the vaccine in adults ages 18 years and older.

The U.S. Centers for Disease Control and Prevention (CDC) eased travel recommendations for more than 110 countries and territories, including Japan just ahead of the Olympics.

Safety concerns about Johnson & Johnson’s Covid-19 vaccine along with overall flagging demand for vaccinations have slowed its U.S. rollout to a crawl, leaving close to half of the 21 million doses produced for the United States sitting unused.

The United States had administered 301,638,578 doses of Covid-19 vaccines in the country and distributed 371,520,735 doses as of the morning of June 6, the U.S. Centers for Disease Control and Prevention said.

Speculation regarding poorer outcomes for those with high cholesterol and/or heart disease infected with SARS-CoV-2 are well known. A real-world study published by the FH Foundation confirms Covid-19 increased heart attack rates significantly in patients with these conditions. 

The United States reported the lowest number of new Covid-19 cases in nearly a year for the week ended May 23, with new infections dropping 26 percent from the previous seven days to just under 180,000, according to a Reuters analysis of state and county data.

Pfizer Inc. began testing fully vaccinated adults over 65 in a new study that uses the company’s 20-valent pneumococcal conjugate.

Some teenagers and young adults who received Covid-19 vaccines experienced heart inflammation, a U.S. Centers for Disease Control and Prevention advisory group said, recommending further study of the rare condition.

Texas Governor Greg Abbott on May 18 ordered all government entities in the state, including school districts, to lift mask mandates by week’s end, though existing guidelines for face-coverings in schools may remain in effect through June 4.
