Reacting to the previous wave of COVID-19 Omicron type, the Australian government is launching the newly formulated XBB 1.5 Vaccine Australia. This new vaccine version has been formulated to boost the immune system and better respond to newer Omicron sub-variants.
So, what can we expect from this new vaccine? Read on to learn more about how the XBB 1.5 vaccine Australia can protect you from COVID-19 and how it compares to the previous ones!
What is an XBB 1.5 Vaccine Australia?
The XBB.1.5 is a COVID-19 vaccine designed to combat the Omicron XBB.1.5 strain of SARS-CoV-2. This monovalent vaccine helps produce antibodies, which improve protection against newer Omicron variants.
A recent study found that the XBB.1.5 is categorised as a variant of interest by health authorities due to its ability to evade immune responses, complicating treatment in immunocompromised populations.
How is It Different from Previous COVID-19 Vaccines?
The newer version of the XBB.1.5 vaccine specifically targets the Omicron XBB.1.5 strain of SARS-CoV-2. Meanwhile, the previous COVID-19 vaccines target earlier strains of COVID-19, especially the original Wuhan strain, which became less widespread across the country.
Experts also added that focusing only on the first strain of the virus could lead to a risk of a weakened immune response to new vaccine components designed for sub variants. Hence, getting a dose of the newer vaccine version is recommended.
Which XBB.1.5 COVID-19 Vaccines are Available in Australia, and Who Should Get Vaccinated?
Based on the Australian Technical Advisory Group on Immunisation (ATAGI) guide on the Australian Government Department of Health and Aged Care page, there are three available XBB.1.5 vaccines in Australia with different doses of COVID-19 vaccine, including:
- Low-dose Pfizer monovalent XBB.1.5 (light blue cap): This is formulated for children 5-11 years old who are eligible for a primary or additional dose. It contains 10mcg of the SARS-CoV-2 XBB.1.5 Omicron subvariant spike protein mRNA.
- High-dose Pfizer monovalent XBB.1.5 (dark grey cap): This is formulated for people aged 12 years and older who are eligible for a primary or additional dose. It contains 30mcg of the SARS-CoV-2 XBB.1.5 Omicron subvariant spike protein mRNA.
- Moderna monovalent XBB.1.5 (pre-filled syringe): This is formulated for people aged ≥12 years old who are eligible for a primary or additional dose. It contains 50mcg of the SARS-CoV-2 XBB.1.5 Omicron subvariant spike protein mRNA.
Meanwhile, children aged 6 months to 4 years old are not eligible for this new vaccine.
How Does the Side Effect Profile Compare to Previous COVID-19 Vaccines?
The side effects of the XBB.1.5 COVID-19 vaccines (Pfizer and Moderna) are similar to those of earlier COVID-19 vaccines, including the original and bivalent versions.
So, what were the side effects of the previous vaccines?
Most people who receive the XBB.1.5 The COVID-19 vaccine experienced no side effects in the first three days. The most common side effect for those who do is a local reaction at the injection site (pain, redness, swelling, itching).
Other side effects include fatigue, muscle or joint pain, and headache.
Data revealed that fewer people experienced side effects from the Pfizer XBB.1.5 Vaccine than the Moderna XBB.1.5 Vaccine. Also, only a few people missed work or daily activities due to side effects and needed medical attention.
Frequently Asked Questions
Is Pfizer or Moderna XBB better?
Both Pfizer and Moderna XBB.1.5 vaccines have similar safety and side effect profiles and are effective.
How effective is the XBB.1.5 vaccine?
The XBB.1.5 vaccine’s effectiveness is reliable. It can reduce the risk of severe illness, hospitalisation, and death from COVID-19, especially in preventing infections caused by the XBB.1.5 subvariant.
Is XBB.1.5 an omicron variant?
Yes, XBB.1.5 is a subvariant of the Omicron variant of SARS-CoV-2.
Conclusion
The XBB 1.5 vaccine in Australia offers targeted protection against the newer Omicron subvariants, enhancing immune response compared to previous COVID-19 vaccines. With Pfizer and Moderna options available for different age groups, staying updated and receiving the most effective protection against COVID-19 is crucial.
