A pair of new studies that sized up how COVID-19 vaccines affected hospitalizations, including during the Omicron variant surge, found that mRNA vaccines were highly effective against severe illness and that unvaccinated people were 12 times more likely to be hospitalized compared with those who had received a booster, with the risk especially high in Black patients.In other COVID-19 developments, Moderna yesterday file for approval for emergency use for fourth doses of its mRNA vaccine as surges in Asian hot spots continued at very high levels.Vaccines, boosters crucial toolThe authors of both studies assessed how well vaccination protected against hospitalization during the worst of the Omicron surge and compared it with how well the vaccines held up during the Delta surge.

Both studies were published today in Morbidity and Mortality Weekly Report (MMWR).The first study examined how mRNA vaccines protected against the most severe outcomes, defined as ventilator treatment or death.

The authors looked for any differences between patients who had gotten their primary series and those who had also received a third dose.The case-control study is based on data from a multistate hospital network and included adults ages 18 and older who were hospitalized with COVID-19 symptoms from Mar 11, 2021 through Jan 23, 2022.

Of 7,544 patients, 1,440 had lab-confirmed COVID and 6,104 controls tested negative.Patients who received two or three doses had a 90% reduced risk for ventilator treatment or death from COVID-19.

(Britta Pedersen/picture alliance via Getty Image)Researchers have documented evidence of microplastics found in human blood for the first time, according to a recent study conducted in the Netherlands. The study, published in the journal Environment International on March 24, observed the blood of 22 healthy, non-fasting volunteers and subsequently, 17 out of the 22 people tested positive for having microplastics in their blood. Researchers found four "high production volume polymers" in test subjects’ blood which included polyethylene terephthalate, a synthetic resin which is often found in clothing fibers, containers for liquids and food and found in food in general, according to the study. In addition, polyethylene, one of the most common types of plastics primarily used in packaging for food, medical tubing and cable wires was also detected in the subject’s blood. Also present was polymers of styrene, otherwise known as polystyrene, which is made "from the monomer styrene, a liquid hydrocarbon that is commercially manufactured from petroleum," according to Science Direct. Polystyrene is widely used in the food industry to create containers, cups, utensils, plates and bowls. Researchers found approximately 1.6 micrograms (one-millionth of a gram) of microplastics in blood samples.

Quebec should plan mass campaign to give out COVID-19 booster shots: vaccine committee
COVID-19 vaccine fourth-dose campaign for the general population that would be launched in the fall.Quebecers most vulnerable to serious consequences from the disease — seniors over 80, immunocompromised people and residents of long-term care homes — can start receiving a fourth dose of vaccine next week, health officials said Wednesday. The same day, the immunization committee said the government should start planning to give second boosters out to everyone in a few months.In a written opinion released Thursday, the Comité sur l’immunisation du Québec recommended the government implement “a new vaccine strategy aimed at periodically boosting immunity against COVID-19 while also allowing for the ability to react to a possible emergence of a new variant of concern.”Quebec to offer 4th dose of COVID-19 vaccine to at-risk groups as cases, hospitalizations riseA mass second-booster campaign, the committee suggested, could take place in September or October and target “either all persons authorized to receive vaccines against COVID-19, or those usually targeted by the seasonal influenza vaccination program.”Currently, only 52 per cent of the population aged five and older have received a third dose of vaccine, according to provincial health data.The committee released an analysis of hospitalizations and deaths that occurred between January and mid-March indicating that people 80 and older were almost 200 times more likely to die of COVID-19 than those under 60, and 16 times more likely to be hospitalized.
