Mix-and-match booster shots shown more effective against Omicron strainA letter yesterday in the New England Journal of Medicine (NEJM) from Centers for Disease Control and Prevention scientists shows homologous (same-vaccine) boosting for Johnson & Johnson (J&J) vaccine recipients was significantly less effective than mix-and-match booster doses when the Omicron strain was predominant in the United States.Approximately 18 million Americans received the one-dose J&J vaccine as their primary COVID-19 vaccine.

The study tracked COVID-19 cases among J&J recipients with no booster, a J&J booster, an mRNA booster, and adults who received three doses of mRNA vaccine (a primary series plus a booster).The investigators collected data from Jan 2 to Mar 23, 2022, from the Increasing Community Access to Testing (ICATT) platform, which reported results from drive-through testing sites, and included adults who had reported vaccination status.

The authors found vaccine effectiveness was highest for the regimens that included a booster dose of an mRNA vaccine and was lowest for those who received a single J&J shot.Single-dose J&J efficacy was 17.8% (95% confidence interval [CI], 4.3% to 29.5%) compared to no vaccination from 14 days to 1 month after the shot, and 8.4% (95% CI, 1.5 to 14.8) from 2 to 4 months since receipt of the vaccine.For recipients who received a J&J booster dose after a J&J primary vaccine, efficacy was 27.9% (95% CI, 18.3% to 36.5%) 14 days to 1 month after boost, and 29.2% (95% CI, 23.1% to 34.8%) 2 to 4 months after boost.

In adults who received J&J plus an mRNA booster, efficacy was 61.3% (95% CI, 58.4% to 64.0%) and 54.3% (95% CI, 52.2% to 56.3%), similar to rates seen in those with three mRNA doses: 68.9%

High gas prices bring demand for fuel to record lows ahead of peak driving season
LOS ANGELES - Gas prices are so high that demand for fuel during peak driving season this summer is expected to slump, according to experts.According to data by the Energy Information Administration compiled by Bloomberg, demand for gas has hit its lowest level during this time since 2013, excluding the impacts of the ongoing COVID-19 pandemic. Overall, high gas prices have brought demand down by 5%.Gas prices have been hitting fresh records for the past 11 consecutive days amid the energy supply crunch in the U.S., according to the American Automobile Association (AAA), which noted that the stretch of record-high prices as the pump is "unprecedented."Speaking with Fox News Digital, Andrew Gross, the national spokesman for AAA Inc. revealed that drivers should expect elevated prices throughout the summer, especially if the war in Ukraine rages on.The national average for a gallon of gas was $4.59 last week, a slight increase from the day before and a new record high.Thursday’s record was 16 cents higher than the week before, nearly 50 cents higher than the month before and $1.55 more compared to the same time last year.All 50 states had a national retail price over $4 a gallon on Thursday, according to AAA, with Oklahoma offering the cheapest gas at $4.03 a gallon and California offering the most expensive gas with an average of $6.06.
