What are first, second and third waves of infections?

Waves of an illness occur when daily rates of infections increase over time, reach a peak, then decrease more over time. Many different characteristics determine what makes a wave occur in each region but certain aspects remain the same.

Do the Seychelles have the highest global vaccination rate and the biggest COVID-19 surge?

Seychelles has the highest percentage of vaccinated people in the country per capita. Though the nation is dealing with a current surge in cases, it does not have the world's biggest surge in terms of total cases or as a percentage of its population.

NZ scientists to lead largest-ever vaccine monitoring study

A global collaboration helmed in New Zealand will help assess the safety of COVID-19 vaccines on a massive scale. The Global Vaccine Data Network (GVDN) at the University of Auckland, with its 21 partners in 17 countries, has been awarded funds by the US Centers for Disease Control and Prevention (CDC) to monitor 300 million people for vaccine side-effects.

Australian state of Victoria announces 7-day circuit breaker lockdown to combat highly infectious variant of concern

It has just been reported that the state of Victoria, Australia will enter a seven-day circuit breaker lockdown from 11:59pm tonight in a bid to curb the state’s growing coronavirus outbreak caused by a highly infectious variant of concern. In a press conference, Acting Premier James Merlino said there are now 34 active cases of coronavirus in Victoria, with 12 linked new cases in the past day. Mr Merlino said the primary concern is how quickly this strain is moving. The State Government is urging everyone to get vaccinated and has said getting vaccinated will be one of five reasons people are allowed to leave home.

German preprint giving theory about why blood clots might rarely occur after vector-based COVID-19 vaccines

A preprint, an unpublished non-peer reviewed study, from researchers in Germany presents a theory for why vector-based COVID-19 vaccines, such as Oxford-AstraZeneca and Johnson & Johnson, may cause rare blood clots.

Eigenschaften und Verbreitung der SARS-CoV-2-Variante B.1.617.2

Die ursprünglich aus Indien stammende Variante B.1.617.2 des SARS-CoV-2-Virus breitet sich trotz niedriger Inzidenzen weiter in Großbritannien aus. Britische Forschende schätzen, dass sie sich 50 Prozent schneller verbreiten kann als die vorherrschende Variante B.1.1.7. Im Mai wurde sie daher auch von der Weltgesundheitsorganisation als „Variant of Concern“ (VOC) eingestuft, wie zuvor auch schon B.1.1.7. Aufgrund der raschen Verbreitung von B.1.617.2 in Großbritannien beobachten britische Wissenschaftlerinnen und Wissenschaftler die Entwicklung ganz genau, charakterisieren die Variante im Labor und modellieren ihre weitere Verbreitung. Das SMC hat zwei von ihnen gebeten, ihre neuen Erkenntnisse in einem virtuellen Press Briefing zu berichten und Ihre Fragen zu beantworten. Außerdem möchten wir gerne einen Blick in die Zukunft werfen und besprechen, welche potenziellen Varianten anhand des derzeitigen Wissenstandes noch zu erwarten sind und wie diese mit dem Impffortschritt wechselwirken.

Are COVID-19 vaccines causing antibody-dependent enhancement?

As of May 2021, there is no evidence to suggest that COVID-19 vaccines are leading to antibody-dependent enhancement.

PHE on vaccine effectiveness against the B.1.617.2 ‘Indian’ variant

A preprint from Public Health England (PHE) looks at the effectiveness of COVID-19 vaccines against the B.1.617.2 variant first identified in India.

Are vaccine injections emitting electric and magnetic fields?

None of the COVID-19 vaccines approved for emergency use contain any metals or use any radiation technology that would emit high levels of electric and magnetic fields (EMF).


近期台灣疫情升溫,引發大眾擔憂若印度變種病毒進入台灣,是否可能引發更嚴重的傳播疫情,以及懷疑疫苗是否也會因此失去保護力。在5月10日,世界衛生組織(WHO)宣布,在印度被發現的新冠變種病毒「B.1.617」(印度變種),由VOI(值得關注的變異,Variant of Interest),升級為VOC(需留意的變異,Variant of Concern)。世界衛生組織新冠疫情技術總監范科霍芙(Maria van Kerkhove)在記者會中指出:「已經有研究指出B.1.617能夠更輕易人傳人,傳播力更強」。研究顯示「B.1.617」除了傳播力更強,還具有更強的致病能力。

Can people get the COVID-19 vaccine alongside other immunizations?

The United States Centers for Disease Control and Prevention recently stated that they believe it is safe to administer COVID-19 vaccines at the same time as other vaccines. However, vaccines given on the same day should be injected in different areas, there is uncertainty about whether or not giving two or more different vaccines at once may cause worse side effects, or if vaccines containing weakened live viruses might require different guidance. At this time, the World Health Organization has not issued new recommendations for administering different vaccines at the same time as a COVID-19 vaccine, though it has listed the AstraZeneca vaccines for emergency use. This vaccine contains a weakened live pathogen so health regulators may decide if it is safe to administer this vaccine at the same time as others.

Can people receive three jabs of Sinovac's CoronaVac vaccine?

We do not yet know if Sinovac's COVID-19 third dose is safe or effective. A third injection is being tested in a Chinese clinical trial now. It is not recommended to have a third vaccine dose until more data has been studied and it has been deemed safe by health organizations.

What happens if you get an expired vaccine?

Getting any expired vaccine can mean that you are not protected as well or at all from a disease. It’s also possible that certain inactive vaccines could cause harmful reactions, but there are not many documented cases of this happening, and no documented cases of this happening with COVID-19 vaccines. Because COVID-19 manufacturers were very cautious in setting expiration dates, it’s possible that COVID-19 vaccines are effective for a short period of time even after the set expiration date.
