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.
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 continue to evolve for months after a COVID infection has cleared.
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.
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.
Maintaining antibodies in the blood requires creating certain long-lasting immune cells – but this doesn’t always happen.
We mapped the genes of B cells to better understand why some develop immunity and others don’t.
Researchers don’t fully understand the composition of breast milk and its benefits. Beyond nutrition, it contains enzymes, hormones and the mother’s antibodies — including antibodies for COVID-19.
The results indicate that the vaccine efficacy in the UK was 89% for individuals who received at least two doses of vaccine. In South Africa, the vaccine efficacy was 60% in people without HIV.
A biologist explains what proteins do in viruses, how they interact with human cells, how the vaccine delivers mRNA into the cell and how antibodies protect us.
Long-term protection will depend on the ‘memory response’ developed by our immune systems – and the initial signs are promising.
With vaccine shortages looming, experts are debating whether it is important to receive two doses or whether it’s better to give one dose to more people and give a second when the supply is better.
A new study has shown that there are sex-based differences in how we respond to the coronavirus.
A new discovery offers hope for ways to treat a debilitating disease that has become a leading cause of death in the US..
Some have suggested the US allow healthy people to return to normal life, catch the coronavirus and get the population to herd immunity. The science says this plan is doomed to fail from the start.
Antibody levels naturally fade – the key question is whether infected people sustain adequate levels of T cells and B cells.
Are antibodies that attack a patient’s own organs contributing to severe forms of COVID-19? A new study suggests specific antibody tests that may reveal the answer.
Vaccines work by teaching your immune system about new viruses. Your immune cells are very clever – they will remember what they learnt, and protect you if you encounter that virus in the future.
Will a vaccine for COVID-19 be safe? Animal testing, human clinical trials and post-approval surveillance give us good grounds to believe that a future approved vaccine will work and be safe.
