The Conversation: What’s Australia’s first local Pfizer-style COVID vaccine? And when might it be in our arms? An mRNA expert explains
A research team at Monash University are working on developing Australia’s first mRNA vaccine candidate, with phase 1 trials set to begin in October or November this year.
Although the vaccine under development works by the same principles as the Pfizer and Moderna vaccines by using a genetic code called RNA to spark the production of the coronavirus’s specific spike protein, there are key notable differences.
Firstly, the Monash mRNA vaccine directs cells to make a small part of the spike protein, the receptor binding domain. The receptor binding domain is the tip of the spike protein which is the part that is mutating to form new variants of COVID disease. Targeting this part of the spike protein allows variant-specific responses, for which there is a strong clinical need.
Secondly, existing vaccines are modelled on the original strain of the virus first detected in Wuhan, however, the Monash mRNA vaccine has since been changed to sequence the Beta strain – a strain which was first detected in South Africa for which vaccines created from the original variant are less effective.
This highlights the flexibility of mRNA vaccines with sequences being able to be changed and adapted to new variants that have emerged and that may emerge in the future.
Plans are underway for the vaccine to be developed locally, an important step in developing Australia’s capacity for mRNA vaccine production and the newly developing Australian RNA biotechnology sector overall.

RACGP: Government announces new vaccine counselling MBS item number
Federal Health Minister Greg Hunt has announced the introduction of a newly-created MBS item in response to rising vaccine hesitancy related to widespread reporting the rare condition, thrombosis with thrombocytopenia syndrome, following receipt of the COVID-19 AstraZeneca vaccine. The new Medicare item, known as the Level B equivalent, will provide patients over 50 with a $38.75 rebate when receiving COVID vaccine counselling from their GP.
The introduction of this scheme will allow more time for GPs to address patient concerns and provide support in making informed decisions seen as crucial to boosting vaccination rates.

ATAGI 关于使用 COVID-19 疫苗阿斯利康的修订建议声明,2021 年 6 月 17 日
ATAGI has revised the recommendations for COVID-19 vaccination within Australia.
Due to a higher risk and severity of thrombosis with thrombycytopenia syndrome (TTS) related to the use of COVID-19 AstraZeneca, Comirnaty™ is now the preferred COVID-19 vaccine for individuals aged 16-59 years. Due to the risk of severe outcomes related to COVID-19 disease for individuals aged 60 years and over, the benefits of vaccination in preventing disease outweighs the risk of developing TTS.
Individuals aged less than 60 years who have received their first dose of COVID-19 AstraZeneca without any serious adverse events (eg. anaphylaxis or TTS) should continue to receive their second dose.

纽约时报:耗资数十亿美元的计划很快就会结束脊髓灰质炎
全球根除脊髓灰质炎行动宣布了一项 $51 亿美元的计划,到 2026 年在全球范围内根除脊髓灰质炎。2021 年 8 月,非洲国家宣布消灭野生脊髓灰质炎,阿富汗和巴基斯坦成为仅存的地方病国家。由于资金不足和缺乏政治承诺,以前在实现无脊髓灰质炎世界方面取得的成功有限。冠状病毒大流行增加了更多挑战,导致一些脊髓灰质炎疫苗接种计划停止。
新计划将侧重于两个关键目标:将脊髓灰质炎疫苗接种计划与其他医疗保健计划相结合,并重点关注免疫接种率长期较低的地区。该计划还确保疫苗供应并概述了提高疫苗接受度的沟通策略。除此之外,还引入了一种新的口服疫苗,并被认为可以最大限度地降低疫苗引起的脊髓灰质炎的风险。
根除脊髓灰质炎计划的一个关键重点是为难以到达的社区提供免疫接种,并培训年长的女性卫生工作者,她们更能成功地说服护理人员为孩子接种疫苗。为了恢复将根除脊髓灰质炎作为优先事项,即使在这些现金匮乏的国家面临竞争激烈的健康挑战,专家认为,旨在消灭脊髓灰质炎的计划也可用于帮助管理 COVID-19 和其他疾病。

美国广播公司:随着阿斯利康的供应即将到期,巴布亚新几内亚想出了创造性的方法来为人们接种疫苗
巴布亚新几内亚 (PNG) 的 COVID-19 疫苗接种速度缓慢,据信是由于错误信息的影响。随着阿斯利康 (AstraZeneca) 的 COVID-19 疫苗库存即将到期,我们采取了一些创造性举措来提高疫苗的使用量。
这些举措包括开发巴布亚新几内亚第一个移动疫苗接种单位——一辆黄色巴士。巴士将疫苗运送到社区,使当地人能够看到疫苗接种过程的实际情况。
疫苗接种所需的所有用品、疫苗和应急设备都可以通过巴士运往村庄,其中一些村庄没有自己的卫生诊所。这项由社区主导的举措使人们能够向医疗服务提供者寻求信息,以克服犹豫和错误信息并接种疫苗。
随着广泛的社区传播,重点仍然是鼓励医护人员以及符合条件的社区成员(例如老年人和患有合并症的人)接种疫苗。

RANZCOG 和 ATAGI 关于孕妇接种 COVID-19 疫苗的联合声明
澳大利亚和新西兰皇家妇产科学院 (RANZCOG) 和 ATAGI 发布了一份关于 COVID-19 疫苗和孕妇的联合声明。
建议孕妇在怀孕的任何阶段常规服用 Comirnaty™。提出此建议的依据是,如果孕妇患上 COVID-19 疾病,孕妇及其未出生的婴儿出现严重后果的风险会增加
该建议反映了国际数据的结果,该数据尚未发现孕妇接种 mRNA COVID-19 疫苗后出现任何安全信号。此外,在接种疫苗的妇女的脐带血和母乳中检测到了抗体,这表明保护作用转移到了婴儿身上,

RACGP - 澳大利亚当局更新了阿斯利康疫苗的副作用建议
继近期 联合声明 ATAGI 以及澳大利亚和新西兰血栓与止血协会 (THANZ) 的 RACGP 确认,几乎任何 50 岁以上的人都可以安全地接种阿斯利康疫苗。该声明还澄清了与某些群体使用阿斯利康疫苗有关的罕见凝血病症 - 血栓形成伴血小板减少症候群 (TTS) – 现在可以得到有效治疗。
最新发布的信息还证实,患有以下疾病的人患 TTS 的风险不太可能增加(这些人群中 50 岁以上的人仍然可以接种阿斯利康疫苗):
- 典型部位有血栓史
- 非免疫介导的凝血倾向增加
- 有血栓家族史
- 缺血性心脏病或中风病史
- 当前或过去的血小板减少症(血小板计数低)
- 接受抗凝治疗的人
此外,ATAGI/THANZ 声明还报告称 英国数据 表明第二次注射后 TTS 的风险要低得多,迄今为止,在 900 万次注射中仅报告了 15 例病例,也就是说每百万剂中估计有 1.7 例病例。
