There is immense interest in understanding whether potentially protective SARS-CoV-2 antibodies are provided to the baby via breast milk. This is what we know so far.
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.
Public health officials have been waiting for good data before making any decisions about booster shots for people who received Johnson & Johnson’s Janssen COVID-19 vaccine.

Your body produces antibodies after an infection or vaccine, but these slowly decline over time. New Johnson & Johnson data sheds light on the duration of protection and the need for booster shots.
New discovery could help scientists develop more targeted drugs and vaccines.
People getting vaccinated may still have questions about COVID-19 vaccines, like why it takes two doses — and then two weeks — to take full effect.

A medical student answers questions he gets asked at a COVID-19 vaccine clinic: Efficacy versus real-world effectiveness, immune response and how the mRNA vaccines compare to vaccines already in wide use.
By better communicating how vaccines boost the immune system’s long term “memory”, manufacturers could address vaccine hesitancy.
Cell-mediated immunity is particularly effective at eradicating viruses, and more durable. This is important in the fight against COVID-19.
A little more than 8% of vaccinated people in the U.S. have received the Johnson & Johnson vaccine.

It has been six months since the Johnson & Johnson vaccine received emergency use authorization. What does six months of data show about its efficacy, side effects and protection from variants?
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.
A French study found a four to sixfold reduction in neutralisation against the delta variant compared with the alpha (Kent) variant.
The freedom of going mask-free is still a ways off for kids under age 12.

As many teens and adults in the US restart their social lives, parents of children under the age of 12 wonder when their kids will also be able to experience the freedom that comes with vaccination.
Can you really fake a covid test with soft drinks?
There’s a way for parents to spot the fraud.
The latest advice is to offer COVID-19 vaccines to women at any stage of pregnancy to protect them from a higher risk of severe disease – and to give their babies an early boost of antibodies.

Variants of the original SARS-CoV-2 are now in wide circulation. That means the third wave of COVID-19 has come with new questions about the variants, their effects and what might come next.
Immunity to COVID-19 appears to be generated in different ways in different subgroups of people.
Vaccination produces a much stronger and more consistent immune response than infection.

If you’ve already had the coronavirus and recovered, you might be tempted to give the vaccine a pass. A scientist explains why the shot offers the best protection against future infection.
Antibodies (white) binding to a coronavirus (red and orange).
Antibodies continue to evolve for months after a COVID infection has cleared.
New mRNA vaccines use genes from the coronavirus to produce immunity.

So far, most vaccines in the US are mRNA vaccines. These represent a new technology and are likely to take over the vaccine world. But how do they work? What are their weaknesses? Five experts explain.
New treatments target different stages of COVID-19, including before patients become sick enough to need a hospital.

A year after it became clear that COVID-19 was becoming a pandemic, there is still no cure, but doctors have several innovative treatments. Some are keeping patients out of the hospital entirely.
Antibodies (blue) neutralising SARS-CoV-2 (orange), the virus that causes COVID-19.
Maintaining antibodies in the blood requires creating certain long-lasting immune cells – but this doesn’t always happen.
