Is vitamin B6 safe? How much is too much? And will I still be able to buy my supplement over the counter?

It is almost impossible for vitamin B6 toxicity to occur from diet alone.
Cases of tuberculosis have been detected in South Australia over the past 17 months. Here’s what you need to know about the disease.
Cases of the flu and COVID are set to rise over winter, with many people looking to get vaccinated against both viruses.
If you’re aged 30 or over and it’s been three months since you either had COVID or received your last COVID vaccine, you’re eligible for a booster.
The COVID isolation period is seven days in Australia, but you might still be infectious after that if you have symptoms and a positive RAT.
Far from a mild disease, the flu can cause serious illness and death, particularly among children and older age groups. The flu vaccine isn’t perfect, but it’s the best way to protect yourself.
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?
Many Australians are yet to have a third COVID vaccine dose, while people overseas are having their fourth shot.
A vaccinated person is less likely to get COVID, is less contagious, and is contagious for a shorter time.
Regulators are currently reviewing the safety and efficacy data of the Pfizer vaccine for five to 11 year olds before deciding whether to approve its use in this age group.
But the immune cells that vaccination spurs do last a long time.
Some countries have started administering third doses of COVID vaccines, or booster shots. But we’re still learning about how long immunity lasts from the first two shots.
While there are plausible explanations for why this occurs, we can’t be certain of the effect of temperature on SARS-CoV-2. Being indoors in poorly ventilated spaces plays a big role.
Researchers around the world are using new and existing technology to develop potential treatments for those with COVID-19. Here’s what’s in development in Australia.
La « thrombocytopénie immunitaire prothrombotique induite par le vaccin », ou TIPIV, comme l’appellent les scientifiques, se caractérise par un manque de plaquettes dans le sang.
Scientists have called it “vaccine-induced prothrombotic immune thrombocytopenia”, or VIPIT. The condition is characterised by a shortage of platelets in the blood.
Over 130 million doses have already been administered worldwide. It’s early days, but the signs are promising in places like Israel and the UK.
Moderna’s shot is far easier to store and distribute than Pfizer’s. But there are concerns neither vaccine performs particularly well for older people.
Coronavirus is surging in Spain, France, Germany and the UK, after many countries relaxed restrictions over the summer. They should look to success stories like Vietnam.
The way we deliver vaccines continues to evolve. Here’s a look at needle-free vaccine technologies from history to the modern day.
This is just one person. Is he the exception? Is he the rule? We don’t know yet for sure. But reinfection is definitely possible.
We’re cleaning and washing our hands perhaps more than we ever have before. But suggestions that all this this extra hygiene could weaken our immune systems are unfounded.
Victoria recorded 484 new cases on a day when COVID-19 should have been firmly on the decline if the latest lockdown was working. It’s time to contemplate even stricter measures for longer-term gain.
The evidence on whether wearing masks and gloves in the community will actually protect against coronavirus isn’t strong. But if you’re going to take these precautions, you might as well do it right.
