(Reuters.) – Here is a list of recent COVID-19 studies. There is some research that needs to be further investigated to verify the results and has yet to receive peer review certification.

COVID-19 worsens asthma in children

Doctors warn that children with asthma may be more sensitive to the coronavirus infection.

Nearly 62,000 children in America with asthma had PCR testing for the virus during the initial year of the pandemic. More than 7,700 were positive. Infected children had significantly more asthma visits, hospitalizations, emergency inhaler use, and steroid treatments during the six months after their illness compared to children who tested negative and to their own prior history, researchers reported in the Journal of Allergy and Clinical Immunology: In Practice https://www.jaci-inpractice.org/article/S2213-2198(22)00360-9/fulltext. Children who had tested positive for the virus showed improved asthma control, with fewer asthma hospitalizations, emergency department visits, and steroid treatment.

She said that earlier research showing an improvement in asthma control during the first year of the pandemic was likely due to public measures such as staying at home or masking which reduced exposure to triggers. Chou stated that although children suffering from asthma were generally able to control their symptoms during the first year, this new study has shown “longer lasting damage by COVID” on asthma control in children.

Booster after infection adds little extra benefit vs Omicron

A third dose of the mRNA vaccine Pfizer/BioNTech is available to people with coronavirus infection. Moderna According to recent data, Omicron may not increase their resistance against the virus.

Nearly 130,000 Connecticutans were tested for COVID between November 2021 and January 2022. This included 10,676 Omicron-infected individuals. Roughly 6% to 8% had been infected with previous versions of the coronavirus, according to a report posted on medRxiv https://www.medrxiv.org/content/10.1101/2022.04.19.22274056v3 ahead of peer review. Margaret Lind from Yale University stated that Omicron was protected by two doses mRNA vaccine. But, “we didn’t detect any additional benefit to receiving a third dose among this population.”

A separate study from Canada, also posted on medRxiv https://www.medrxiv.org/content/10.1101/2022.04.29.22274455v1 ahead of peer review, similarly found that more than two vaccine doses “may be of marginal incremental value” for protecting previously-infected individuals against Omicron. Lind said that “(1) people should have two doses mRNA vaccination regardless of prior infected status, and (2) those with no prior infected need to get another dose. (3) People who are high-risk for developing life-threatening complications should seek out a booster vaccine. But, they should recognize that this booster dose may not offer significant protection against Omicron.
