New Vaccine Against Tuberculosis
VPM1002 is the new BCG vaccine to be produced by the
Serum Institute at Pune, India. It was developed by the Max Plank
Institute for Infection Biology, Berlin. For this vaccine, BCG has been
genetically modified by deletion of the Urease C gene and expression of
the listeriolysin. At a small scale in animals and humans, it was found
to be safer and more effective than BCG. Phase 1 trials in adults in
Germany and South Africa, and a Phase 2a trial in 50 newborns in South
Africa have been promising. A Phase 2b trial is currently underway in
infants born to HIV positive or negative mothers. This will be followed
by Phase III trials in newborns and adults in India.
The new vaccine has been found to be safe even in
HIV-infected patients, and is expected to protect against
extra-pulmonary tuberculosis. Another interesting finding has been the
formation of protective antibodies. So far, antibodies were not
considered useful against tuberculosis as it is an intracellular
pathogen. In contrast to natural M. tuberculosis infection,
pre-existing antibodies stimulated by prior vaccination could directly
attack M. tuberculosis at the port of entry, and may contribute
to vaccine efficacy. This option has thus far been largely ignored in
tuberculosis vaccine design. An effective vaccine against tuberculosis
is much required and long awaited. (The Hindu 21 February 2016).
Health in the Union Budget
The Finance Minister of India has announced The
Health Protection Scheme of Rs. 100,000 to cover unforeseen illness in
poor families with an additional Rs. 30,000 for senior citizens. The
government also plans to add 3,000 pharmacies under the Jan Aushadhi
Yojana to provide generic drugs at affordable rates. The Minister
also announced the launch of a National Dialysis Program to deal with
the high costs involved in renal dialysis processes. As part of the
program, every district hospital will have facilities of renal dialysis.
However, child health interventions have received a
massive cut from Rs 15,483.77 crore to Rs 14,000 crore this year. The
integrated Child Development scheme (ICDS) has received a 7% reduction
in funds; Mid-Day Meal scheme is also badly hit. The total union budget
allocation has gone down from 0.74% in 2014-15 to 0.49% in 2015-116.
Last year too, the government had slashed funds to the Women and Child
Development Ministry by 50% compared to the previous year. (The Times
of India 1 March 2016, The Hindu 3 March 2016).
Fruit and Vegetable Intakes – India’s Report
The WHO recommends 400g of fruit and vegetable intake
per day (5 servings of 80g each) to provide adequate phytonutrients to
prevent chronic diseases. A report on the fruit and vegetable
consumption in India was recently released by the ICRIER (Indian Council
for Research on International Economic Relations) in New Delhi. The
survey included 1000 individuals across 5 upper- and middle-income
groups across India. The average intake was 3.5 servings per day which
included 1.5 servings of fruits and 2 servings of vegetables.
Eighty-nine percent of respondents were not aware of the WHO
recommendations. Causes for low intakes included lifestyle, seasonal
availability and high cost. The level of food processing is low in India
(2.2%), and about 18% of fruits and vegetables are wasted in the supply
chain. The intake in rural areas is likely to be much lower, despite
India being a largely vegetarian country. (The Hindu 7 February 2016).
Reducing Antibiotic Prescriptions
Authorities in UK conducted an interesting study to
reduce antibiotic usage. General Practitioners (GPs), whose antibiotic
prescription rates were in the top 20% for their local National Health
scheme areas, were randomized into two groups. Every GP in the
intervention group was sent a letter from England’s Chief Medical
Officer and a leaflet on antibiotics for use with patients. The letter
stated that the practice was prescribing antibiotics at a higher rate
than 80% of practices in its NHS Local Area Team. GPs in the control
group received no communication. There was a significant reduction in
prescription rate of antibiotics by GP’s who received the letter,
resulting in an estimated 73,406 fewer antibiotic items dispensed.
Social norm feedback from a high-profile messenger can substantially
reduce antibiotic prescribing at low cost and at national scale. (The
Lancet 18 February 2016).
