If you are 18 years or older and live in an area where there is an outbreak of Kovid-19, then the same vaccine is best for you, then you should get it immediately. This simply means that you should get the AstraZeneca vaccine, as Pfizer’s supply is still short. The advice was given by the Australian government’s specialist vaccine advisory body ATAGI (Australian Technical Advisory Group on Immunity) on 24 July. Why did the body give them this new advice after months ago advising young people to prioritize Pfizer?
Is the Delta version more dangerous for youth?
Indeed, during the new outbreak of the pandemic in Australia, where the Delta variant has a greater impact, more young people are being hospitalized and admitted to the ICU, and the death toll is also higher. It can now be a matter of debate whether the delta variant is more dangerous for young people and whether young people are more vulnerable to it because the elderly have already been protected by vaccination.
However, there is little room for debate that the Delta strain is more contagious, which is why we want to vaccinate our population as soon as possible. So if you are 18 years of age or older and have not yet been vaccinated, you may be asking whether getting the AstraZeneca vaccine right now is the right thing for you to do. To answer this we need to consider the benefits and risks of the AstraZeneca vaccination.
What should be gained from the vaccine?
When thinking about what should be achieved by administering any COVID-19 vaccine, there is an order of priority. First, then it should stop people who are victims of Kovid from dying. Second, it should reduce the risk of serious illness (symptomatic so bad that ICU treatment is required). third, hospitalization should be less. If a vaccine is doing more than these three things, it’s a bonus.
We are very lucky that the AstraZeneca and Pfizer vaccines not only do all three of these things, they also reduce the number of people suffering from any type of illness (including mild symptoms), and possibly reduce transmission (COVID-19). People exposed to -19 become less infectious).
Do vaccines work against the delta variant?
As Delta has become the dominant strain of COVID-19 around the world, researchers are working hard to see how well current vaccines perform against it. So far, the news is good. Let’s look at the proof.
Delta has less effect on a person vaccinated
In the UK, where the delta variant currently accounts for the majority of infections, there were 229218 Covid infections between February and July. Of these, 12.5% were fully vaccinated. These are known to be successful infections (because they ‘break’ the protection of the vaccine). Of those successful transitions, 3.8% required going to the ED. Only 2.9% had to be hospitalized, and less than 1% died.

This means that even though vaccines did not completely protect people from disease, they did achieve their primary purpose: saving lives and keeping people from going to the hospital. Another study in the UK that was limited to those hospitalized with the Delta strain concluded that AstraZeneca is 92% effective against hospitalization after two doses. Other studies have shown a 60% to 67% reduction in symptomatic disease.
Although AstraZeneca works to reduce the infectivity of the Delta strain, people who are vaccinated can still transmit the disease to others. That’s why it’s so important for vaccinated people to still follow all other evidence-based methods, including wearing masks, social distancing and lockdown restrictions – at least until we have enough people in the community vaccinated Doesn’t happen
But what are the risks?
There are of course potential risks from the AstraZeneca vaccine: injection site pain, fatigue, headache, muscle aches, fever, and chills are the most commonly reported side effects. Most of these are mild and temporary, getting better in one to two days. There are also rare but serious side effects: anaphylaxis (two to five per million people), and thrombosis with thrombocytopenia (TTS).
