Graphene oxide content of COVID-19 vaccines in Hong Kong

This request has been reported as needing administrator attention (perhaps because it is vexatious, or a request for personal information)

Dear Sir or Madam,

Please can you provide the following information.

1. How much graphene oxide - or other graphene compound(s) - do each of the COVID-19 vaccines authorized for emergency use in Hong Kong contain, as a percentage by mass or by volume?

Thank you in advance for your assistance in this matter.

Yours faithfully,

Paul Jackson

Department of Health

Dear Paul,

Thank you for your email of 2 August 2021 seeking access to information
relating to graphene oxide content of COVID-19 vaccines in Hong Kong.  

Currently, two COVID-19 vaccines, CoronaVac and Comirnaty are authorized
for emergency use in Hong Kong.

Ingredients of the vaccines can be found in vaccines package inserts
accessible via the COVID-19 Vaccination Programme thematic webpage:
CoronaVac under "Composition":

Comirnaty under "6.1 List of excipients":
[2]https://www.covidvaccine.gov.hk/pdf/SmPC...

If we can be of any assistance in the provision of other information in
the future, please do not hesitate to contact us again

Dear Paul,

Thank you for your email of 5 August 2021 seeking access to information
relating to influenza deaths and vaccination data from 2015-2020.  

Seasonal influenza is a common respiratory infectious disease in Hong
Kong, which occurs throughout the year, especially during the influenza
season. For healthy individuals, seasonal influenza is usually
self-limiting with recovery in days, without the need of laboratory
confirmation.  Also, seasonal influenza is not a statutory notifiable
disease in Hong Kong.  The Centre for Health Protection (CHP) of the
Department of Health does not have the information on the number of people
diagnosed with influenza locally.

The CHP monitors the seasonal influenza activity in the community through
various surveillance systems, such as severe influenza cases in intensive
care unit (ICU) admissions and/or deaths with laboratory confirmation
among adult patients.  These cases refer to laboratory-confirmed influenza
patients who required ICU admission or died within the same admission.
 The causes for ICU admission or death may be due to other acute medical
conditions or underlying diseases.  In addition, cases not admitted to
hospitals/ICUs and/or do not have laboratory tests performed (etc.) are
not included in the surveillance data.  
According to the recommendation of the Scientific Committee on Vaccine
Preventable Diseases (SCVPD), children aged 6 months to 11 years is one of
the priority groups to receive seasonal influenza vaccination (SIV). The
SCVPD commented that “seasonal influenza vaccination is recommended for
children aged 6 months to 11 years for reducing influenza related
complications such as excess hospitalisations or deaths. Studies in
overseas have shown that vaccinating young school children may potentially
 reduce  school  absenteeism  and  influenza  transmission  in the
community.” For details, please refer to the following link:
[1]https://www.chp.gov.hk/files/pdf/scvpd_r....
The DH therefore launched the School Outreach Vaccination Pilot Programme
(Pilot Programme) in October 2018 to provide free SIV to eligible primary
school students, so as to increase their SIV coverage. The SIV coverage
for children between 6 years to less than 12 years increases from 20.5% in
2017/18 to 55.4% in 2018/19.

If we can be of any assistance in the provision of other information in
the future, please do not hesitate to contact us again.

Influenza Deaths and Vaccinations Data 2015-2020

Dear Oma, Francis,

Thank you for your reply.

It has taken me some time to study the information via the links you
provided.
I found the following information on deaths attributed to influenza in
each of the winter influenza seasons only, searching CHP's own releases
plus info.gov.hk and The Standard:

2015: 502 deaths total
2016: 214 deaths total
2017:    41 adult and one child deaths
2018: 382 adult and two child deaths
2019: 356 adult and one child deaths
2020: 113 adult and no child deaths
2021: one adult and no child deaths to 22 March 2021

The average annual winter season influenza deaths over the first five
"pre-COVID-19" years was thus a fraction under 300, and that obviously
does not include influenza deaths outside the main peak season.

In your response, you stated that DH does not have the answer to my
original Q1, but I was able to find it from other HKSARG sources including
CHP itself.

Furthermore, while you provided the requested statistics for Q2, with an
age breakdown as requested in Q6, but did not explain how you measured,
quantified or estimated the benefit of the influenza vaccinations.

I had requested a key metric by which one could evaluate the benefit of
influenza vaccinations.

From the figures you provided, it seems that there were particularly large
increases in influenza vaccinations of 50-64 year olds due to the
extension of the GVP, and of eligible primary students due to the Pilot
Programme, comparing 2018 and 2019 with 2016 and 2015.

But where are the benefits seen in the overall influenza deaths data?

You state that "Given the effectiveness of the Pilot Programme, ..." for
children and explain its extension to more primary schools, kindergartens
and childcare centres.

Please can you explain how you measured the effectiveness of the Pilot
Programme for children. It is clear that the huge increase in government
vaccination of children has made little or no difference to influenza
deaths among children, which are thankfully extremely rare. Has it made a
significant difference to critical cases of influenza among children? Or
school days lost?

Similarly, for the large increase in influenza vaccinations of the 50-64
year olds. Since I do not have the age stratified deaths due to influenza,
it is impossible for me to observe anything in particular relating to
adults of that age range. Again, the overall influenza vaccinations have
certainly increased dramatically, but, up to 2019, there does not appear
to have been any obvious benefit in reduced mortality due to influenza.

Please can you explain how you quantitatively evaluate the effectiveness
of influenza vaccines.

Yours sincerely,

Paul Jackson
