Australian fitness leader Paul Kelly said, “Everything indicates that this is the beginning of a new wave of COVID-19 in Australia. “
XBB appears to be able to spread faster than the BA. 5 variant of omicron, but so far there is no definitive evidence that it causes more severe disease. BQ. 1 comprises mutations that help the virus evade existing immunity. This means that infection with other subvariants, add BA. 5, which contributed to the COVID wave in Australia in the middle of the year, would probably not do so with BQ. 1.
The most productive coverage against severe COVID, regardless of circulating subvariant, is to ensure that booster shots have been won. So who is eligible?
Current coverage
More than 95% of Australians over the age of 16 have gained two doses. But while a third dose is for anyone over the age of 16, just over 70% have gained a third dose (as of Nov. 3).
ATAGI also recommends that a momentary booster (fourth dose) be given to other people over the age of 50, other people over the age of 16 living in care facilities for the elderly or other people with disabilities, and those over the age of 16 who are seriously immunocompromised or have a medical condition that increases the threat of severe COVID.
People in their 30s and 30s can have a reminder moment if they wish.
A booster dose of COVID is also for other people over the age of five to five who:
Despite advice from the Australian Technical Advisory Group on Immunization (ATAGI), only two-thirds of those over 65 and only one-third of those over 30 have gained a fourth dose.
Then we have room for the politics of our booster doses.
What booster shot do I receive?
We now have COVID vaccines of the original strain and recently two bivalent COVID mRNA vaccines were provisionally used as booster vaccines in Australia.
Bivalent mRNA vaccines (one manufactured through Moderna and the other manufactured through Pfizer) are adapted vaccines that cause an immune reaction opposite to two other COVID variants: the original virus and the BA. 1 omicron variant. Moderna’s bivalent vaccine is now available and Pfizer is coming soon.
For others 18 years of age and older, the original Moderna, bivalent Moderna, original Pfizer or bivalent Pfizer vaccines are the preferred vaccines for a booster dose.
The AstraZeneca or Novavax COVID vaccines would possibly be used as booster doses in other people 18 years of age and older who have a contraindication, or who have had anaphylaxis or myocarditis (inflammation of the central muscle) after a previous dose of mRNA vaccine (Pfizer or Moderna) or prefer not to get the mRNA vaccine.
The period between the end of the number one COVID vaccination cycle (the current dose for the maximum of other people) and the first booster dose is 3 months. The period between the first booster dose and the current booster dose (for other people) is 3 months.
Are dual-purpose reinforcements better?
A recent clinical trial involving more than 800 participants showed that antibody responses to omicron were superior after the bivalent Moderna vaccine (original and BA1) administered as a fourth dose of the original Moderna vaccine strain.
A trial of Pfizer’s bivalent vaccine (original and BA1) also demonstrated superior antibody responses to omicron BA1 against the original vaccine strain.
The protection of the two bivalent mRNA booster vaccines is similar to that reported after an original booster. The maximum local adverse reactions reported after a momentary booster dose of Moderna bivalent vaccine were injection site pain (77%), fatigue (55%), headache. (44%) and muscle pain (40%).
The TGA relied on this knowledge of Pfizer and Moderna clinical trials to tentatively approve the two bivalent vaccines.
What happens to antibodies after infection?
Antibody levels after Moderna’s two booster shots (original and bivalent) are higher in other people who have already had an infection than in those who have not had an infection in the past.
It is to examine antibody responses after a booster shot in those who have already had COVID. In fact, recent serological studies (looking for antibodies in blood samples) imply that two-thirds of us have already had a COVID infection.
Booster doses are recommended to be given at least 3 months after the herbal infection, as immunity to infection decreases over time and it is possible for others to become reinfected.
A booster dose in those who have already gained 3 doses of the vaccine and an herbal infection produces higher levels of antibodies. However, it is not yet known how effective the fourth dose of the bivalent vaccine is in preventing infections in others who have already been infected.
Usa. The U. S. government also has bivalent booster vaccines, but has “updated” vaccines involving the original strain of SARS-CoV-2 (the virus that causes COVID) and the BA. 4 and BA. 5 variant or SARS-CoV-2.
The United States has allowed vaccines to be updated based on knowledge of animal controls and has not required knowledge of human controls. Human trials are underway and effects are expected soon. After this, corporations are very likely to apply, with effects from human trials. , to the TGA for approval.
Bottom Line
The truth is that COVID is not over. We are probably already entering a wave of infection, but the severity of the new variants in Australia is not yet known with certainty.
