According to scientists we’re experiencing a new wave of covid ‘largely’ thanks to the BA.4 and BA.5 omicron variants that we’ve mentioned before. The surge has seen at least 1.7m people in the UK catch covid for the first time, a second time, or even a third time.
The latest week-on-week increase of 23% is worrying the medical community. The 130% hike we’ve seen in just three weeks is very concerning. But the government isn’t offering any advice so far. Medical experts are taking it more seriously. They recommend we revert to only socialising outdoors.
So how likely are you to be re-infected if you’ve already had covid? Are the jabs you’ve had still working to protect you? And if you get BA.4 or BA.5, how will it affect you?
Catching omicron doesn’t give you good immunity against getting BA.4 and BA.5
When the omicron variant arrived here in December 2021 the reinfection rate shot up 15-fold thanks to the variant’s many mutations. It escaped established immunity in many of us, which is why so many people who’d been vaccinated or had covid already caught it all over again earlier this year.
Catching omicron doesn’t give you much protection against catching covid again simply because having had the original omicron doesn’t help the immune system fight off BA.4 and BA.5. If you caught omicron, there’s no reason why you won’t catch BA.4 or BA.5. On the other hand it remains rare for someone who has already had covid to be reinfected within 3 months.
How about the vaccinations you’ve had?
The BA.4 and BA.5 sub-variants both have new mutations that weren’t found in the original omicron variant.
This means, even if you’ve had all three jabs, you’re still vulnerable to the new sub-variants.
According to an article in Nature magazine both of the new sub-variants ‘notably evade the neutralising antibodies elicited by SARS-CoV-2 infection and vaccination’. The same goes for booster jabs based on the BA.1 subvariant, for example Pfizer/BioNTech and Moderna. They don’t offer broad-spectrum protection against new omicron variants either. But it’s good to know that despite covid’s clever immune evasion, the vaccines we’ve had should still protect us against serious illness.
The most important thing of all? If you’re due a jab, have a jab. It’s vital stay up to date with vaccinations because they maintain good levels of covid antibodies in your bloodstream.
If you do catch covid again, what can you expect?
As a rule covid is milder the second or third time we catch it, thanks to residual immunity. But because the two sub-variants have probably evolved to focus on infecting lung cells once more, going lower down inside the lungs rather than affecting the upper respiratory tract, they have more in common with the earlier, more severe alpha and delta variants. All this means BA.4 and BA.5 could prove a greater health risk than the original BA.2. We just don’t know yet.
There’s no government guidance – So what should you do?
There’s no government guidance so far, even though a new study reveals people who’ve had covid face a potential three times bigger risk of ‘permanent decline’ in their health. No wonder medical experts say it’s best to avoid infection or reinfection, just in case it hits you hard. Scientists are saying the same, since every extra person that catches covid increases the risk of an even worse variant developing.
If you run a business, the last thing you want is to have large numbers of people off sick, potentially staying off for at least five days. Everyone who gets covid faces the risk of developing Long Covid, which could see some of your employees unable to work for a long time, potentially as long as two years or more.
All this puts you, as a business owner, in a tricky position. How do you keep your employees safe and well, and keep the people who visit your place free from covid as well?
