We know that the incidence of thrombocytopaenic thrombosis syndrome (TTS) can occur with the AstraZeneca (AZ) Covid-19 vaccines although it is pretty uncommon. What do you do with patients who had TTS with the first jab and it’s now ready for the next jab? Obviously, they can’t have the second jab with AZ.…

It’s all too confusing. And annoying. They keep releasing updates in the lay media and says “see your GP to discuss” but did not update us. You will recall that 2 weeks ago the recommendations to have the second AstraZeneca vaccination moved to 6 weeks after the first vaccination in areas with the outbreak which is pretty much all of Sydney.…

We all know that detailed information relating to Covid-19 is both fluid and rapidly changing. It’s only a mere 3 months since the first reports of thrombosis with thrombocytopaenia (TTS) relating to the administration of the AstraZeneca (AZ) vaccine emerged from Austria. The recommendations as to who should not have the AZ vaccine is constantly being revised as more information comes in from the case reports.…

Thrombosis with thrombocytopaenia syndrome (TTS) has been reported following vaccination with AstraZeneca (AZ) and Johnson and Johnson (JJ) covid-19 vaccines. It is also called VITT (vaccine-induced immune thrombotic syndrome) and VIPIT (vaccine-induced prothrombotic immune thrombocytopenia). It is rare and primarily occurs in those under 50 years old. Although the government recommend that people under 50 years have the Pfizer vaccine, there are people who are in Phase 1A and 1B who can’t and should not wait for the Pfizer vaccine where supplies are limited.…

Every time the government overpromise and underdeliver, we are the ones that have to deal with the public whose expectations have been led unnecessarily high for political reasons. With the issue of clots relating to the AZ vaccine on the front page over the last week or so, patients are now utterly confused and look to their GP for advice as to where and when to proceed.…

Last week we explored the association of thromboembolism following vaccination with AstraZeneca (AZ) vaccine. This adverse event was first reported in two patients in Austria which is then followed by more reports in Germany and the rest of Europe. One man in Victoria was recently reported to have similar adverse effects following the AZ vaccine.…

It all started when the Austrian regulatory authority suspended the use of a batch of AstraZeneca (AZ) vaccine on March 9th after a patient was diagnosed with multiple thrombosis and died 10 days after vaccination, and another was hospitalised with pulmonary embolism after being vaccinated. At least 16 other countries follow suit and suspended the use of AZ vaccine.…

I know we have touched on this vaccine before when we discussed Covid-19 vaccine candidates. We briefly discussed the interim results then but since we are likely to get the AstraZeneca/Oxford (AZO) vaccine in the national vaccine roll-out in primary care, there will be many questions coming from our patients in the coming weeks.…

So, here we are. It’s almost 12 months since the beginning of the Covid-19 pandemic. A number of vaccines will become available within weeks. GPs can’t be the sole provider of the vaccines but we will a major part of the vaccination roll out program. We haven’t heard much from NSW Health on how the program will be rolled out, which will be the first subgroups we will be vaccinating nor will the vaccine ordering system be better than last year’s influenza vaccination program.…
