Research on microneedle patches for vaccine delivery has grown in popularity in recent years, due to their exceptional compliance and low invasiveness.

The vaccines remain protective against serious disease and death.

The organization implored nations to wait on booster shots until the global vaccination rate increases, but several of the world’s more well-off countries have expressed their intentions to offer them regardless.

Immune-response levels to the edible vaccine varied among the subjects, possibly due to differences in the gut microbiome.

More than a dozen vaccines for tuberculosis are currently being tested in clinical trials. Some use whole bacteria as BCG does, while others deliver protein subunits or genetic material carried by viral vectors.  

This month marks the 100-year anniversary of BCG, still the only approved vaccine against the lethal pathogen. But there are new vaccines for this wily foe on the horizon.

Scientists use a protein found in mucus membranes to ferry vaccines to the lymph nodes.

By avoiding the production of antibodies, something vaccines ordinarily induce, the immunization sidesteps the problem of antibody-dependent enhancement, which can amplify infection by a similar virus and is known to occur with dengue and Zika.

While some experts speculate the variant could be partially responsible for India’s current surge in SARS-CoV-2 infections, information about the effects of its mutations is only beginning to emerge.

Politicians should of course consider and respect the latest research findings in crafting policy, but elected officials should honor the scientific method by letting its practitioners hash out the details of the science.

Immunization had up to 77 percent efficacy in a Phase 2 clinical study of 450 children in Burkina Faso.

It’s unclear how long protections against infection will last from the initial vaccinations, and health authorities say additional jabs will likely be necessary.

The chance of developing cerebral venous sinus thrombosis was nearly 10 times higher in the two weeks following a diagnosis of SARS-CoV-2 infection than after receiving an mRNA vaccine, a data analysis finds.

Vaccinations with the Johnson & Johnson jab paused at several sites earlier this week after an unusual number of people experienced adverse reactions, but the CDC says there’s no cause for concern.

The European Medicines Agency emphasizes that the benefits of the jab in protecting against COVID-19 still far outweigh the risks.

One hundred years after its invention, BCG has stood the test of time as a vaccine against tuberculosis.

Rollouts of the shot have ground to a halt following reports of blood clots, but health authorities say that these fears are unfounded and vaccination programs should continue.

Johnson & Johnson’s one-shot immunization could reach people’s arms as early as March 2.

In a triumph for science, COVID-19 statistics are finally trending favorably in the US. We must make sure the rest of the world is not left behind.
