Ever wondered how much the Indian map changed over time?

It’s not only the India-Pakistan partition I talk about; it’s the change in the map of India from 1 AD to the 20th century. An amateur historian named Thomas Lessman has caught these series of shifts. His maps provide a vivid history; they start from 1 AD till the rule of the Delhi Sultanate.

On his Website, Lessman says ” I started drawing maps right after I started reading about history. My earliest maps were crude hand-drawings, but now I’ve got a good computer, a great image program (PhotoShop), and a nice background map. I became frustrated while researching history because it’s hard to find great maps. The best maps are in books that cost more than I make in a week… So I realised if I want free World History Maps, I’d have to make them myself”, mentioned May 2015.

Here the important eras are taken into account that changed the look of map of India:

i. The Indo-Parthian and Indo-Synthian era: 1 AD

If one follows the above map, we can see that there exist Indo-Parthian rule and the Indo-Synthian kingdom during this era. Indo-Greeks ruled India for over two centuries, however, the Indo-Scythians migrated from southern Siberia and displaced the Indo-Greeks.

ii. The Kushan Empire: 100 AD

The 100 AD marked the era of Kushan Empire. It was founded under Kujula Kadphises but it was under his grandson, the Buddhist emperor Kanishka, that it reached its peak.

iii. The Gupta and Huna Empire: 400 – 500 AD

Some people called the period from 400-500 AD the ‘Golden Age of India.’ This was the period, which marked the domination of The Gupta and Huna Empire – 400 – 500 AD. The word Golden Age comes from the fact that during this time, literature, art, astronomy, and math flourished in the region.

iv. The Chalukyas: 600 AD

They dominated over southern and central India from 6th to 12th century. The key aspect of this era was the Chakulyan architecture, which along with Kannada and Telugu literature thrived all along their time.

v. The Ghaznavid Empire: 1206–1526

The Ghaznavid Empire moved in and conquered India and finally the Delhi Sultanate. The Delhi Sultanate was a Delhi-based Muslim kingdom that stretched over large parts of the country. The fall of Ghaznavid Empire eventually led to the rise of the Mughal rule in India.

Pentavalent vaccine: Doctors raise red flag

In spite of the data presented in this paper from a large cohort, the authors point out that the evidence is merely circumstantial and not conclusive

the new Hepatitis B vaccine for adults is called Heplisav-B.
India's PV to be reexamined because of its harmful effects. .
  • Pentavalent vaccine was introduced in India six years ago
  • It is since then have been a cause of many deaths
  • Doctors want it to be reexamined before continuing its use

Pentavalent vaccine (PV), that was introduced by India a little over six years ago, doubled the deaths of children soon after vaccination compared to the DPT (Diphtheria-Pertussis-Tetanus) vaccine, according to a new study that calls for a “rigorous review of the deaths following vaccination with PV”.

Government records show that there were 10,612 deaths following vaccination (both PV and DPT) in the last 10 years. There was a huge increase in these numbers in 2017, which the Health Ministry has promised to study. “The present analysis could be a starting point in the quest to reduce the numbers of such deaths,” authors of the new study say.

The study by Dr Jacob Puliyel, Head of Pediatrics at St Stephens Hospital, and Dr V. Sreenivas, Professor of Biostatistics at the All-India Institute of Medical Sciences (AIIMS), both in New Delhi, is published in the peer-reviewed Medical Journal of Dr D.Y. Patil University.

PV is a combination of the DPT vaccine and two more vaccines against Haemophilus influenza type B (Hib) and hepatitis B. Starting December 2011, PV was introduced into India’s immunisation programme to replace DPT vaccine in a staged manner with a view to adding protection against Hib and Hepatitis B without increasing the number of injections given to infants.

But sporadic reports of unexplained deaths following immunisation with PV had been a matter of concern. Puliyel, Sreenivas and their colleagues undertook the study to find out if these deaths were merely coincidental or vaccine-induced.

The authors obtained data of all deaths reported from April 2012 to May 2016 under the Right to Information Act. Data on deaths within 72 hours of administering DPT and PV from different states were used.

For their study, the authors assumed that all deaths within 72 hours of receiving DPT are natural deaths. Using this figure as the baseline, they presumed that any increase in the number of deaths above this baseline among children receiving PV must be caused by this vaccine.

According to their analysis of the data provided by the government, there were 237 deaths within 72 hours of administering the Pentavalent vaccine — twice the death rate among infants who received DPT vaccine.

Extrapolating the data, the authors have estimated that vaccination of 26 million children each year in India would result in 122 additional deaths within 72 hours, due to the switch from DPT to PV.

“There is likely to be 7,020 to 8,190 deaths from PV each year if data from states with the better reporting, namely Manipur and Chandigarh, are projected nationwide,” their report says.

The authors note that while the study looks at the short-term increase in deaths (within three days of vaccination) it does not calculate the potential benefits of PV on infant mortality, for example by protection against lethal diseases like Haemophilus influenza.

In spite of the data presented in this paper from a large cohort, the authors point out that the evidence is merely circumstantial and not conclusive. “These findings of differential death rates between DPT and PV do call for further rigorous prospective population-based investigations,” the study concludes.
