The immune system usually stays dormant in the lungs in times of health.

While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.
Viral surveillance and prediction may be key parts of figuring out what goes into a vaccine.

A new generation of vaccines and boosters against SARS-CoV-2 may take a page from the anti-influenza playbook, with shots periodically tailored to target the most commonly circulating virus strains.
COVID cases are predicted to rise as we face another variant. So a 4th shot to top up our immunity is looking more likely as we head into winter.
Researchers are working to develop vaccines that provide long-term immune protection from COVID-19.

Because COVID-19 is a relatively new virus, researchers still aren’t sure exactly how long vaccines and prior infections provide protection.
Immunologists are studying how the SARS-CoV-2 virus interacts with antibodies in the immune system.

COVID-19 has taken away so much. An immunology researcher describes the good it may leave behind.
The Novavax COVID vaccine is now available in Australia. What makes it different from the other vaccines? And why are some people waiting for it to get vaccinated?
Taking OM85 could lower the risk of developing asthma by protecting babies’ lungs from damaging infections in the early years of life.
One study suggests the virus takes an average of 36 days to clear from the body after symptoms first appear.
Variant-specific vaccines would undoubtedly increase immunity. But waves of new variants would engulf the population faster than these vaccines could ever be deployed.
There’s not enough evidence yet to support the AstraZeneca CEO’s statement. But it is theoretically plausible.

The development of COVID vaccines has already been explosive. There are more innovations on the way.
Many vaccine formulations are tweaked for patients of different ages.

First CDC signed off on a COVID-19 vaccine for adults, then teens. Now US children ages 5 to 11 are officially eligible for shots. Here’s the science on why each group needs to be considered separately.
Protection from infection wanes over time. So boosters will offer extra protection and hopefully reduce the spread of the virus even further.
Pregnancy poses significant risks for severe illness or death from COVID-19, for both mother and baby.

In light of mounting research showing the serious risks of contracting COVID-19 during pregnancy, the CDC is re-upping its urgency that pregnant women get their shots.
But the immune cells that vaccination spurs do last a long time.
The estimated lifetime costs of antiretroviral therapy for someone who acquires HIV at age 35 is $358,380.

People with HIV need to take daily medication to keep the virus at bay. A study has found that a new treatment combination could boost immunity and control virus levels even after stopping medication.
No third dose for now.

An FDA panel has voted against recommending approval of a booster COVID-19 shot for the general population – disappointing some public health officials.
‘Breakthrough’ infections can happen because of waning immunity or high viral doses. But our vaccines are still excellent at preventing severe disease and death.
Despite rampant misinformation, studies show that COVID-19 vaccines are safe for both the mom and baby.

A COVID-19 vaccine does not cause infertility – but it can protect you from the dangerous complications of contracting the virus.
Recovering from COVID and then getting vaccinated, known as hybrid immunity, is more potent than being infected or vaccinated alone.
