Any COVID-19 vaccine is likely to be given first to higher risk groups before it is given to children. But we still need vaccines that are safe and effective for them too.
Pregnant women are routinely excluded from clinical trials for drugs and vaccines.
Pregnant women are at increased risk for serious COVID-19 complications and should be a high-priority group for vaccination. Excluding them from vaccine trials puts them and their offspring at risk.
There are many scientific and ethical challenges ahead. But these types of trials have helped in the development of vaccines against a few diseases. Could they do the same for COVID-19?
Australia's contribution to the global COVAX initiative helps secure future vaccines. Here's the full field of candidates.

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.
Stoppages of clinical trials are a normal part of the testing process, and show that patient safety is being taken seriously.

The COVID-19 vaccine is in the final stages of testing – meaning we should know whether it's effective before the end of the year.
There is a lack of good clinical research on the advantages of blue-light filtering lenses.
Some health products haven't been tested for the benefits that they claim to produce. Blue-light blocking lenses are promoted as helping sleep cycles, but there is no evidence to support this.

The head lice drug ivermectin is being touted as a coronavirus killer. But studies suggest it would need to be taken in mega-doses far higher than those currently used, with unknown side-effects.

As Russia fast tracks a coronavirus vaccine, scientists worry about skipped safety checks – and the potential fallout for trust in vaccines if something ends up going wrong.
As antimicrobial resistance increases, the options for treating serious infections dwindle. Doctors need reliable information about which treatments to try out.
Further tests are needed but a trial showed that, when compared against placebo treatment, those given the drug had a 79% lower risk of developing severe disease.
The race is on to develop a vaccine for the COVID-19 coronavirus. Australian researchers are leading several major clinical trials that might help bring an end to the deadly disease.
Researchers are central to any country’s science preparedness, especially in the face of pandemics.

Amyotrophic lateral sclerosis, Lou Gehrig's disease, is a crippling, progressive neurodegenerative disease for which there is no cure. Now it seems that a diabetes drug may help some cases.
Vaccinologists have not focused their research on tailoring vaccines to induce robust immune responses in the elderly.
Immunosenescence — the decline of immune system function with age — means that vaccines are not as effective in older adults, the demographic most susceptible to many diseases, including COVID-19.
The experimental vaccine stimulates the creation of antibodies. Now we need to show that these effectively protect us from the coronavirus.
Loneliness affects one in three people in the industrialized world, with racialized groups disproportionately bearing the burden.
Pluralism — the active process of inclusion — could reduce disparities in some of the most pressing health issues of our time.
The lower the vaccine’s effectiveness, the more likely social distancing in some form may still be necessary.

A vaccine that's 70% effective might not be good enough if too few people are willing to be vaccinated, new research shows.
